no we'd be were we are now because theres dumbasses like you stupid enough to believe that. You blame religion for all of your's and the world's problems, but you don't do shit to solve them. Not to mention, if the crusades didnt happen, people would have just found something else to fight about. thats just how humans are. we fight, we do stupid shit, we blame others for our problems even if the fault is our own, but we do nothing to change it. So in reality, dumbfucks like you hurt more than help, you bar people from working together and helping each other, just because they believe something you don't. Why can't their be no such thing as prejudice? This is one of the main problems with the world, not religion. Open your eyes, people.
