I don’t tend to think they are a good idea. Animals can’t give consent to something like that and I don’t think humans should be taking advantage of animals in that way. Obviously, I know you can’t make a hybrid or anything, but you can’t know whether the animal is okay with it and I just don’t think people should do that to animals. Obviously I understand that people don’t choose to be attracted to animals, only a moron would think that. But that doesn’t mean I think you should act on that attraction.
Also, for my own selfish reasons, the people who were against homosexuality will turn around and say “see? what did I tell you? Acceptance of bestiality immediately follows acceptance of homosexuality” and it will only strengthen a case against accepting homosexuality and I wouldn’t want that since I’ve spent so much time pointing out how the two are not connected in any way, which they aren’t.
