Are you a true conservative? True conservatives realize that you can't have it both ways: if you are against government micro-managing what you do on your own property, with your own body, and/or in the privacy of your own bedroom, then you can't also be too terribly hepped up about "the gays." The positions are highly illogical, as Spock would say.
Me? I don't pretend to understand it, really, but I sure as shootin' don't believe it's a choice. Work with me here a minute: until about a millisecond ago (and still today, in many places in the world), being gay was and is a potential death sentence. In many countries, it is still "open season" and you can be killed just for being gay. Our gay veterans, who served our country nobly, were kicked out and given dishonorable discharges (good luck getting another job): even in the absence of any misconduct, and despite being willing to put their lives on the line for you and me, we tossed them aside. What about all the gay kids killed over the years in this country? How on earth do you really think it can be "chosen?" WHY, given what ostracism, hatred, violence and shame they faced/face, would a heterosexual person CHOOSE to be gay? My grandmother, who was born a hundred years ago and was as true-blue a conservative as you'd ever find, always said "Don't hate them. They were born that way." How could they not be? Did you never go to school with a kid that, be nice, everyone knew was gay from kindergarten on? Do none of you really have a gay member of your extended family? Neighbors? Friends? Church community? (If you think not, you are likely wrong).
My son had a friend in high school who came out as gay. Their church, which was the center of his family's life, disowned him and he tried to kill himself. I realized then that the stakes are too high on this issue for those of us who are "straight but not narrow" to stay silent. This is a big country, and a big world, and there is room for everyone, gay and straight. And yes, things are changing. In the US, most people under 40 or so couldn't give 2 figs about someone else's gayness/straightness. They see them as people first. And I for one am glad for that.
I would ask that you view this deeply Christian family's story:
