If you are not 'sexually' attracted to members of the same sex, then you're not gay. If you're sexually attracted to members of the same sex, but abstain from sexual intercourse with members of the same sex, then according to the bible, you're still on the right path.
And yes, heterosexuals practice heterosexuality.
No one said that the individuals themselves were a practice. And no one said being gay is contagious.
As I said before, I have nothing against gay people, I just don't think having sex with members of the same sex is right and I don't condone same sex marriage.
You're confusing me with a homophobe. If I were homophobic, I probably wouldn't even be here right now.
