There’s been a lot of media attention recently to the changing demographics of the United States, where, at current rates, people who identify as “white” are expected to become a minority by the year 2050. But in many ways, the shift in national demographics has been accelerated beyond even that. New data from the American Values Atlas shows that while white people continue to be the majority in all but 4 states in the country, white Christians are the minority in a whopping 19 states. And, nationwide, Americans who identify as Protestant are now in the minority for the first time ever, clocking in at a mere 47 percent of Americans and falling.

The most obvious reason for this change is growing racial diversity. Most Americans still identify as Christian, but “Christian” is a group that is less white and less Protestant than it has been at any time in history. The massive growth in Hispanic Catholics, in particular, has been a major factor in this shift in the ethnic and religious identity of this country. White Catholics used to outnumber Hispanic Catholics 3 to 1 in the 2000s, but now it’s only by a 2 to 1 margin.

But another major reason religious diversity is outpacing the growth of racial/ethnic diversity is largely due to the explosive growth in non-belief among Americans. One in five Americans now identifies as religiously unaffiliated. In 13 states, the “nones” are the largest religious group. Non-religious people now equal Catholics in number, and their proportion is likely to grow dramatically, as young people are by far the most non-religious group in the country. This isn’t some kind of side effect of their youth, either. As Adam Lee has noted, the millennial generation is becoming less religious as they age.

These changes explain the modern political landscape as well as any economic indicator. While not all white Christians are conservative, these changing numbers definitely suggest that conservative Christians are rapidly losing their grip on power. And while some non-white Christians are conservative, their numbers are not making up for what the Christian right is losing. And whether conservative leaders are aware of the exact numbers or not, it’s clear that they sense that change is in the air. Just by speaking to young people, turning on your TV, or reading the Internet, you can sense the way the country is lurching away from conservative Christian values and towards a more liberal, secular outlook. And conservative Christians aren’t taking these changes well at all.

To look at the Christian right now is to see a people who know they are losing power and are desperately trying to reassert dominance before it’s lost altogether. The most obvious example of this is the frenzy of anti-abortion activity in recent years. Anti-choice forces have controlled the Republican Party since the late '70s, but only in the past few years have they concentrated so singlemindedly on trying to destroy legal abortion in wide swaths of the country. In 2011 alone, states passed nearly three times as many abortion restrictions as they had in any previous year.

None of this is a reaction to any changes in people’s sexual behavior or reproductive choices. It’s not like there was a spike in abortions causing this panic. In fact, the abortion rate has been declining. And despite continuing media panic over adolescent sexuality, the fact is that teenagers are waiting longer to have sex, on average, than in the past. Despite this, not only are you seeing a dramatic increase in attacks on legal abortion, the Christian right has expanded its attacks to contraception access, suggesting that something has worked them into a panic they believe can only be resolved by trying to reassert their religious and sexual values.

That something isn’t changes in sexual behavior, but it’s reasonable to believe it’s because of changes in sexual values. People might not be having more sex, but they are feeling less guilty about the sex they are having. Since Gallup first started polling people in 2001 on moral views, acceptance of consensual sex between adults has skyrocketed. In a decade’s time, acceptance of premarital sex swelled from 53% to 66% of Americans and acceptance of gay Americans grew from a mere 38% to a majority of Americans. Even polyamory has become more acceptable for Americans, rising from being accepted by 5% of Americans to 14%.

The fact that these changes in attitude are rising alongside the growth of irreligiosity is not a coincidence. More perhaps even than the 1960s, Americans are in a period of questioning rigid sexual and religious mores, and concluding, in increasing numbers, that they are not down with guilt-tripping people for victimless behavior and demanding conformity for its own sake. Some of them–now a whopping 22% of Americans!–are leaving religion entirely. Some are continuing in their faith but choosing to interpret their values differently than Christian conservatives would like.

And so we see Christian conservatives cracking down in a desperate bid to regain control. They claim that they’re being oppressed by increasing tolerance for religious diversity. They have latched onto, with some success, the claim that “religious freedom” requires giving Christians the right to oppress others. The Republican Party is in complete thrall to the religious right, to the point where giving the Christian right one go-nowhere symbolic bill instead of another one created a major political crisis.

The irony is that this panic-based overreach is just making the situation worse for the Christian right. One of the biggest reasons the secularization trend has accelerated in recent years is that young people see the victim complex and the sex policing of the Christian right and it’s turning them off. And they’re not just rejecting conservative Christianity but the entire idea of organized religion altogether. In other words, the past few years have created a self-perpetuating cycle: Christian conservatives, in a panic over changing demographics, start cracking down. In reaction, more people give up on religion. That causes the Christian right to panic more and crack down more. In the end, Christian conservatives are going to hasten their own demise by trying to save themselves. Not that any of us should be crying for them.
