Rob Tisinai summarizes the view of The Family Research Council et al:
There’s no discrimination against homosexuals because there are no homosexuals. Just homosexual conduct. Homosexuality isn’t a state of being it’s merely a set of actions...This thinking is important when it comes to the “immutability” argument in Constitutional law. Is homosexuality a choice? Our opponents answer by pointing out that the decision to engage in homosexual acts is a choice. People can stop being gay just by stopping themselves from having gay sex. That only makes sense, though, if homosexuality is nothing more than same-sex sex. Obviously, though, it’s a great deal more I was gay before I ever had sex, I’m gay when I’m not having sex, I’m gay right now as I type this (and there’s no man in sight).
