Anti-Muslin sentiment comes about with US citizens when Muslin turn to terrorism and hate. Islam is a religion of hate and enslavement of non-muslins. They use rape and mob like behavior to intimidate peaceful citizens into allowing their expansion of Sharia Law. Islam is not a religion. It's a Cult. This is why the world shunned them from the advancing into most peaceful civilizations. But the world is waking up to Muslin expansion paid for by duped supporters of peaceful nations.
