I like, and agree substantially with Doug Tennapel's take here -

"To clarify, I don't look down on homosexuality, I believe it's unnatural and it's a sin."

and

"... I didn't say "I don't like someone". I said, "It's wrong." My opponents will try to ascribe this to some cultural dislike of homos...I've had gays at my house for Thanksgiving, they've held my children, I volunteered at an AIDS hospice and a gay man died in my arms. So let's just stop the dislike stuff right now."

and

"Finally, if genetic predispostion is some kind of pass for the homosexual then perhaps I'm just predisposed to homophobia at the genetic level. How can you condemn me for action on something as germane to me as the black man's skin? Dumb argument and even you don't believe it. You're using it for another reason..."

and more.
