well, that depends.
homosexuality, bestiality and pedophilia, are all sexual attractions that differ from the majority.
The reason that the latter two are illiagal is because they can lead to negative situations.
But if we take the opinion that people have reinforced throught this debate, that beople are born with their sexuality and there is no way to change it, then you basically have condemned the people who have been "born this way" to live as a danger to others.
And yes people could say the same thing about homosexuality, but i repeat, the latter two are known to have negative results.
So you can say that it is possible to change your orientation (which it is), thus giving those poeple a chance to be deemed "safe", or you can say that you cant, thus conemning others "dangerous" due to something that they had no control over. Thus if you are gay and condemn a pedophile, who had no control over what orientation that he was born with, then you a hypocrite.
No. The reason that the latter two are illegal is because a child and an animal cannot give consent.
