And you obviously learned nothing there, else you wouldn't be quoting Wikipedia as a reliable source. Yes, there were short abberational periods where forced conversions happened--but they were just that---abberations---not matters of doctrine--unlike the massive (and still ongoing) campaign by Islam to forcibly convert the world that WAS and IS a matter of religious doctrine.
"The Cathar residents were given a chance to convert, and the 140 who refused were burned."
Do you expect to actually be taken seriously when you compare trivial incidents like this to the hundreds of thousands (and possibly millions) who died at the hands of expansionist Islam.
My only regret is that the Crusades failed, and didn't completely wipe Islam off the face of the earth, as it so richly deserves.
Why do you take pleasure in the death of the wicked? God does not.
"Say to them: ‘As I live,’ says the Lord God, ‘I have no pleasure in the death of the wicked, but that the wicked turn from his way and live. Turn, turn from your evil ways!" (Ezekiel 33:11)
