Not sure if I can agree that it is a religious thing, pretty sure you're wrong on that one. Certain cultures have norms that often override their particular religion.
Beastiality or Zoophilia is pretty much condemned by all religions. We were founded as a Judao-Christian society, so you're saying that Judaism and or Christianity permit the following behavior?

Umm, your vantage point of the world and other people/religions/cultures needs maturing, dear sir.
