Question about a Catholic High School.?

The Crusades were purely Christians trying to get back the land the Muslims stole from them, and to defend themselves from the Muyslims who were going up to them and saying convert or die, to every Chrictian nation. someone had to stop them, and the Christians tried. They get a bad name because they went crazy twice and just killed many innocent people, because of anger and stuff, but but that was little, and blown out of proportion.. it wasn't right but it wasn't the intent of the crusades. I am a Catholic, i go to a Catholic school and our team is the Crusaders, and yes we are proud of that, we are proud of the Christians being the only ones smart enough to stop the Muslims from taking over the world! it was not as successful as we had hoped, but at least we stood up aganinst the AGRESSORS of the world!
