I do not understand how having sex with an animal is cruel to that animal. After all that is one of their basic and primal instincts. I wholeheartedly do not believe in animal cruelty. But you will never make me believe that sex with an animal is cruel to that animal. It is definitely different in our society, but cruel? How would you like it if someone said that you could not have sex with a partner? Not fun, right? Think about it.
