lol, who the fuck is "stahlin"? and hitler was a catholic. and pol pot came into power thanks to the CIA because they thought it would stop communism. one of many massacres in over a dozen countries in the name of our "freedumbs". don't give me that bullshit, this so-called christian country has slaughtered more innocents than it they care to admit.
But, is it due to "religion"? You just eluded that it is due to our "freedumbs"...not based upon our religion.
Religion is merely a vehicle used by those who want to either pursecute, maim, kill, oppress, denigrate people.
One could use greed, racism, nationalism, sexism the same way.
