Seems like a lot of over-thinking to me, but c'est la vie.
If I spoke to two people, and one of them said "I occasionally like to jerk off to cartoon characters, and some of them have cat's tails or whatever but otherwise my sex life is pretty normal," and the OTHER person said to me, "My favorite sex thing is to get tied up and beat up, or to do that to other people," I know which of the two I'D think was more weird and possibly more "mentally ill."
BUT, that's me. I generally think the whole "Kill all the furries!" mentality has a lot to do with people deflecting from their own "perverted" kinks. "Don't lookit ME, lookit THEM! THEY'RE the weird ones! I'm perfectly fine!" And I'm old enough and have seen enough to know that no, nobody is "fine". Everybody is a "sick pervert" and the rest is just a matter of degree.
