you might say that creationism is a perversion of science , and of course I might think the opposite.
but were you to say that creationists were perverts,....you would be saying something else entirely !
has ake actually used that emotionally charged word "pervert" in reference to homosexuals ?, at least as encompassing all, or even most of them.
but to say that the practise of homosexuality is a perversion of the majority heterosexual practise is not to accuse anyone of being a pervert, in the usual sense, for eg priests preying on children.
