Years ago, back when I was just knee-high to a Bachelor of Arts degree, I came home from college for the weekend. On that Sunday morning, I went to church, and after the service a boy I knew from youth group came up to me. He asked me if I remembered a debate we'd had on a retreat in high school - something about whether gay people can have faith.
I didn't remember that conversation, but I knew what I must have said: something along the lines of, "OF COURSE you can be gay and still have your faith, because you're still a person, and it's just a part of who you are - not a sin, not a turning away from God." Apparently, this boy had taken the opposite view.
So I don't remember the original conversation, but I remember that day in the church, when this boy, who had always been sullen and awkward and now looked happy and confident, like he finally belonged in the world, smiled at me and said, "Well, you were right." And he came out to me, there in the church aisle.
Today is National Coming Out Day, and not being gay doesn't mean you can't "come out" as an ally. You might not find out until later how much it means to someone.
