Conservatives always link bestiality and homosexuality, because they see gay people as no more than animals, subhuman. So of course a subhuman would just fuck everything else subhuman, so they make that fucked up link that having sex with another consenting adult, somehow means you're gearing up to fuck animals.
They or his wife wants to fuck dogs and is projecting.
I never considered that aspect of it, horrible. Bad enough equivocating people that do those things with someone's preference. 'Subhuman' is beyond. I just can't understand caring that much who someone else loves let alone hating for it.
