Dancerman Wrote: Muslims hate Jews and Christians because Mohammed told them that they had to. Not because of the Crusades. The Crusades were an effort to reclaim lands which were Jewish and Christian from the muslim conquerors. Any place of worship Jewish, Christian, or other, could and would be destroyed at will by the muslims who saw (and still see) their mission as assuring that Islam is the only accepted faith or if others don't accept it, they must submit to the rule of muslims (dhimmitude).
