instead of bringing the argument in here, just read the debate.
crap. nevermind, they must have deleted it, it is gone.
i really have no desire to get into it again, but in summary, if an animal is initiating the sex, i don't think it harms the animal to go through with it. disgusting, gross and fucking nasty, yes. harming the animal? nope.
the forum in question that brought the subject up that time was really creepy to read (kind of like a train wreck, i couldn't look away) but these freaks really loved and took care of the animals, and part of their "manifesto" if you will was to not initiate the sexual relationship, to let the animal do it.
anyway, that is all i will say on the subject. as i said in that thread, defending beastiality isn't something i want to do because of the ick factor.
