Okay well that is a bowl full of nonsense.  If I ignore that one group of people is enslaved by another and think I can go to God and justify not helping those people when they asked for my help, I am kidding myself if I think God would be fine with that.  

Jesus Christ did not just condemn the oppressive behavior of individuals, he also condemned the group oppression of the Pharisees and Sadducees and the Romans for that matter.  He also warned that if they did not change their ways God was going to allow their whole way of life and way of structure of their worship collapse around them.  This prophecy did exactly take place 70 years later with the fall of the Great Temple in Jerusalem and later on after that the with the Fall of Rome. 

Catholicism's version of Christianity, because it refuses to act justly and present a true version Christianity on account of its clericalism and sexism, is on the brink of falling too.
