maybe, just maybe, the crusades was the right thing?
I mean, they did not have the MSM or PC back then.
Their purpose was to support fellow Christians and to secure the holy places from destruction.
The First Crusade --- the only one out of seven which was reasonably successful --- did push back the Islamic aggressors and secure the Holy Places.
However, the way the warfare was conducted was often horrible. Great saints to who preached crusades (e.g. St Bernard of Clairvaux, who promoted the Second Crusade) came to regret it as they saw the senseless massacres mount; during the Fourth Crusade, the whole shootin' match was excommunicated by the Pope. Twice, I believe.
So you could say I heartily believe in Crusades in theory. But not in practice.
