Let me be more clear: the Church should have driven them from Europe. Let them practice their religion outside of Christendom. Failure to remove them has resulted in the destruction of it.
Good Catholics kept kicking them out. Bad Catholics and Protestants let them back in. Did you watch my recent videos on Cromwell, Luther, Henry VIII, Napoleon, etc? If you want to know why Jews got let back in, thank your Protestant brothers and sisters!
They also brought Communism to China and Latin America, amongst other things...
