“Don’t most conservatives consider homosexuality to be a “lifestyle choice” anyway? So how can a “lifestyle choice” be a mental disease?”
I think conservatives have consistently maintained that homosexuality is a mental disease, and were unhappy when it was removed from that classification in the 1970s based on nothing but political pressure. Anyone really familiar with the homosexual “lifestyle” could arrive at no other conclusion that these are very sick people.
I wouldn't say I'm "familiar" with the homosexual lifestyle, but there's something that tells me that a penis does not belong in a pile of feces. And jumping from hot tub to hot tub to make that happen as often as possible cannot possibly be anything other than a mental disease. But hey, that's just the way I was raised.
