But during the first crusades a lot of Christians were tricked into fighting via the jewish fable of Prestor John. They were killed and their families that tagged along were taken into slavery. The jews who lent them money for the adventure seized their land and property when they failed to return. Back in their homelands villages and towns were deserted.
You are lacking historical context regarding the reality of the crusades. They, like virtually all wars, were initiated by the bankers (jews) for the purposes of enriching themselves and gaining power over their host populations.
I strongly suggest that you familiarize yourself with reality before taking or calling for any drastic actions because the concision of such behavior will inevitably be a tragedy.
