"School day, time to get up, sleepy head. School day."

Although she's been gone since 1998, my grandmother's words ring in my head just about every morning of my life. That's how MaMe, as I called her, got me out of bed and off to my Catholic school when I was growing up and in her care.

But before I shuffled my way to the bathroom to begin my morning routine, I had to hit the floor on my knees to pray, just as I had the night before.

It was usually The Lord's Prayer ("Our Father who art in heaven, hallowed be thy name...") followed by asking God to watch and guide me through my day until I returned to the safety of my home that evening.

But MaMe (pronounced MAH-me) didn't know that at a very early age her favorite grandson had begun to pray, silently, that God would change him from being different, from having crushes on boys, from being more curious about boys than girls.

By age four or five, I was too young to sexualize my infatuations but I knew that everyone else, including my family and friends, would think it was wrong.

Perhaps it was the conversations I overheard from adults around my hometown of Port Allen, Louisiana, who'd mimic gay people, calling them "funny" or "sissy" or "fagots."

Perhaps it was Sunday mornings at our Baptist church, where preachers taught that liking someone of the same sex was a direct and swift path to hell. And that if that person would just turn to the Lord and confess his sin, then God would change him back into the person He wanted him to be - a person who only had crushes on the opposite sex.

All of which meant that, from a very early age, I began to think I was dirty and that I was going to hell. Can you imagine what that feels like for a kid who was just learning to read and perform basic arithmetic? It was awful.

And talk about guilt - I was a Baptist attending Catholic school!

I prayed the silent prayer for God to change me every chance I got until I started attending college in New York. That's when common sense began to take hold and I realized that no amount of prayer would change me into something that wasn't natural to me.

With my religious upbringing, I'd had the opportunity to study religious doctrine. But I learned from different perspectives, from Catholic Mass on Fridays to Baptist services on Sundays to vacation Bible school in the summer to Bible study with a Jehovah's Witness as a teenager.

As I got older I began to realize that all these people and institutions interpreted the Bible somewhat differently. I had a sort of epiphany: the Bible was about the lessons you learned, not about the events or words.

When I became old enough, intelligent enough and logical enough to discern the difference between metaphor and reality, everything changed. I realized that Jonah living in the belly of a whale was a parable written in the same vein as Dr. Martin Luther King, Jr. saying that he had "been to the mountaintop."

Neither Jonah nor King had actually been to those places. They were metaphors for lessons for those of us who cared to absorb them.

So many of us, especially in the black community and in churches, tend to think that religious teachings happened word for word as they were written in Scripture. I think that's naïve, even dangerous.

That type of thinking - or non-thinking - keeps many religious people enslaved to beliefs that they haven't truly stepped back from and examined.

That type of thinking causes people who are otherwise good to shun and ostracize young gay people.

It causes people to want to control and change people who aren't like them. And who wants to be like someone else?

Imagine if we had allowed Christian doctrines and teachings that supported slavery, segregation and the subjugation of women to pervade our society all the way up until the current moment. What kind of world would that be?

Instead, we got on our knees, just as I did as a little boy, and prayed that slavery, segregation and the subjugation of women would end. In the United States, at least, those prayers have largely been realized.

I'm no longer the member of any church but I do believe in a higher power.

It's time for us, especially black people, to stop trying to pray the gay away and to get on our knees and start praying that the discrimination of gay people ends.

What we're doing to our young gay people now is child abuse. It's plain old bigotry and hatred. And if African-Americans don't know what that feels like in America, I don't know who does.
