An increasingly popular bumper sticker reads, "Guns Don’t Kill People—RELIGION Kills People!" In light of recent events I would add religion kills young people: gay, lesbian, bisexual, and transgender young people.

Perhaps not directly, though. And religion is certainly not the only source of anti-gay sentiment in the culture. But it’s hard to deny that religious voices denouncing LGBT people contribute to the atmosphere in which violence against LGBT people and bullying of LGBT youth can flourish.

The news is filled with the tragedies of teenaged boys who were gay and decided to end their living hell by committing suicide. Maybe they weren’t even gay, but merely perceived to be by their peers, who harassed, taunted, and threatened them unmercifully.

These were real kids with real names. Asher Brown, an eighth grader in Texas, shot himself in the head after endless bullying by classmates and despite attempts by his parents to get school authorities to take his harassment seriously. Seth Walsh hung himself from a tree in his California backyard after relentless bullying by classmates. Asher and Seth were 13-years-old.

Billy Lucas, a 15-year-old high school freshman from Indiana, was only perceived to be gay. But the unrelenting bullying ended with him taking his own life. Seven students in one Minnesota school district have taken their own lives, including three teens.

With the exception of Brown in Texas these suicides are not happening in Bible Belt regions of the country, where we might predict a greater-than-usual regard for religious thought. Instead, they are occurring in states perceived to be more liberal on LGBT issues: California, Minnesota, New Jersey, and Rhode Island.

The case of Tyler Clementi is especially instructive about how far we have to go in accepting our gay, lesbian, bisexual, and transgender children. Clementi was an 18-year-old freshman at Rutgers University whose roommate secretly filmed a sexual encounter he had with another male student and then posted it on the internet.

Think about it. If Tyler had been heterosexual and instead filmed having sex with his girlfriend, it would still be an inappropriate invasion of his privacy and tasteless to post the video online. And it certainly would have been embarrassing for Tyler and the girl. But chances are he would have been the recipient of some congratulatory remarks from friends about what a stud he was. And if he was straight he likely wouldn’t have contemplated—not to mention successfully accomplished—his own suicide by jumping off the George Washington Bridge.

No, Tyler was a victim—not of an inner disturbance of depression or mental illness—but of an external and in part religiously inspired disdain and hatred of gay people.

Despite the progress we’re making on achieving equality under the law and acceptance in society for gay, lesbian, bisexual, and transgender people, why this rash of bullying, paired with self-loathing, ending in suicide? With humility and heartfelt repentance I assert that religion—and its general rejection of homosexuality—plays a crucial role in this crisis.

On the one hand, Religious Right hatemongers and crazies are spewing all sorts of venom and condemnation, all in the name of a loving God. The second-highest-ranking Mormon leader, Boyd K. Packer, recently called same-sex attraction "impure and unnatural" in an act of unspeakable insensitivity at the height of this rash of teen suicides. He declared that it can be cured, and that same-sex unions are morally repugnant and "against God’s law and nature."

Just as many gay kids grow up in these conservative denominations as any other. They are told day in and day out that they are an abomination before God. Just consider the sheer numbers of LGBT kids growing up right now in Roman Catholic, Mormon, and other conservative religious households. The pain and self-loathing caused by such a distortion of God’s will is undeniable and tragic, causing scars and indescribable self-alienation in these young victims.

You don’t have to grow up in a religious household, though, to absorb these religious messages. Not long ago I had a conversation with six gay teens, not one of whom had ever had any formal religious training or influence. Every one of them knew the word "abomination," and every one of them thought that was what God thought of them. They couldn’t have located the Book of Leviticus in the Bible if their lives depended on it yet they had absorbed this message from the antigay air they breathe every day.

Add to that the Minnesota Family Council’s Tom Prichard recently saying that the real cause of the suicides is "homosexual indoctrination," not antigay bullying, and that the students died because they adopted an "unhealthy lifestyle."

Susan Russell from All Saints Episcopal Church in Pasadena, California, points out how ludicrous these statements are in her "An Inch at a Time" blog:

Thirteen and fifteen year olds are not ‘adopting a lifestyle,’ they’re trying to have a life! They’re trying to figure out who they are, who God created them to be and what on earth to do with this confusing bunch of sexual feelings that they’re trying to get a handle on. They need role models for healthy relationships — not judgment and the message that they’re condemned to a life of loneliness, isolation and despair.

On the other hand, what’s the role of more mainline, more progressive denominations such as mainstream Christianity, Judaism, and Islam in these recent tragedies? Mostly silence. And just like in the days of the AIDS organization Act Up, "silence equals death."

It is not enough for good people—religious or otherwise—to simply be feeling more positive toward gay, lesbian, bisexual, and transgender people. Tolerance and a live-and-let-live attitude beats discrimination and abuse by a mile. But it’s not enough. Tolerant people, especially tolerant religious people, need to get over their squeamishness about being vocal advocates and unapologetic supporters of LGBT people. It really is a matter of life and death, as we’ve seen.

I learned this in my dealing with racism. It’s not enough to be tolerant of other races. I benefit from a racist society just by being white. I don’t ever have to use the "n" word, treat any person of color with discourtesy, or even think ill of anyone. But as long as I am not working to dismantle the systemic racism that benefits me, a white man, at the expense of people of color, I am a racist. And my faith calls me to become an anti-racist—pro-active, vocal, and committed.

Some progressive religious groups—the United Church of Christ, Unitarians, Metropolitan Community Church—have long been advocates for LGBT people. The Evangelical Lutheran Church of America has recently made great strides in welcoming gay clergy. And my own Episcopal Church has put itself at great risk on behalf of full inclusion of LGBT people in electing two openly gay priests to be bishops.

Still, even in these progressive churches, there is much to be done.

Cody J. Sanders, a Baptist minister and Ph.D. student in pastoral theology and counseling at Brite Divinity School in Fort Worth, Texas, recently wrote on the Religion Dispatches website about how important it is for churches to act:

Ministers who remain in comfortable silence on sexuality must speak out. Churches that have silently embraced gay and lesbian members for years must publicly hang the welcome banner. How long will we continue to limit and qualify our messages of acceptance, inclusion and embrace for the most vulnerable in order to maintain the comfort of those in our communities of faith who are well served by the status quo? In the current climate, equivocating messages of affirmation are overpowered by the religious rhetoric of hatred. Silence only serves to support the toleration of bullying, violence and exclusion. In the face of what has already become the common occurrence of LGBT teen suicide, how long can we wait to respond?

As good Christians and Jews we must work to change the religious thinking, rhetoric, and practice that communicates to our LGBT children that they are despised by their Creator. We must learn to object to anti-gay jokes the way we learned to tell our friends that we would not tolerate racist jokes. We must demand that our schools not only have antibullying policies, but that they follow through on stopping the practice of bullying. We need to lobby our congressional representatives for the Student Non-Discrimination Act (SNDA, H.R. 4530, S. 3390). And we must proclaim openly, loudly, and often that we love our children unconditionally in the way that God does—always wanting the best and most healthy lives for them.

These bullying behaviors would not exist without the undergirding and the patina of respect provided by religious fervor against LGBT people. It’s time for "tolerant" religious people to acknowledge the straight line between the official anti-gay theologies of their denominations and the deaths of these young people. Nothing short of changing our theology of human sexuality will save these young and precious lives.
