So you'd rather have Europe be Islamic I guess, if you're opposing the crusades
How exactly is not supporting a series of wars of aggression against the Ottoman Empire equivalent to wanting Europe to be Islamic?
I don't care either way to be honest...
I'd prefer Satanism for sure, but I don't really care.
The Crusades resulted in Christians being nearly wiped out from the Eastern Mediterranean. Particularly https://en.wikipedia.org/wiki/Fourth_Crusade
And started(?) Jews being killed in Europe https://en.wikipedia.org/wiki/Rhineland_massacres
