I understood your post to be condemning Muslim religion for practices which we frown upon today, but which were acceptable within that culture at the time.  I believe you singled out the Muslim religion for criticism that could just as easily be aimed at every religion, given that pedophilia and bestiality are practices widespread among all religions, including Christianity. 

King David founded the Hebrew religion and built its first temple in Jerusalem.  Jesus was born into the house of David.  His disciples were the actual founders of the Christian religion, based on the teachings of Jesus.  Your point has some merit, but overall, considering your obvious intent to condemn the Muslim religion, your point is irrelevant.

To repeat, people are people.  99.99% of Muslims live peacefully.  That is probably true of Christians in the US.  Condemnation of an entire people for their religion is irrational, and it results only in unnecessary conflict.
