Everyone, who's not Muslim should agree today, that in the human history, there was no other religion, even remotely as barbaric, distructive, and violent as Islam is.
Leaving aside how badly your English sucks, this is pure horseshit. Anselm, the only contemporary biographer of Charlemagne, and who was raised in Charlemagne's court at Aachen, tells how the Franks went out each year for 40 years to kill Saxons, because they were "pagan." It's a toss-up whether the crusaders were more dangerous to other Christians or to the Muslims. One thing we do know, though, because Christian priests recorded the fact, is that during the first crusade, crusaders killed and ate their Muslim captives. Then there was the Albigensian crusade, with estimates of the number of alleged heretics killed ranging from 7000 to 20,000. When asked how the crusaders were meant to distinguish between who was catholic and who was a heretic, Arnald Amaury, a papal legate, is quoted as saying ‘kill them all; God will recognise his own.' There were, of course, the wars of the Reformation, and the so-called Thirty Years War. That doesn't include those killed by the Inquisition other than the Cathars, nor the alleged witches burned in the Protestant countries.
It's not just old times, either, although your idiotic claim is that the Muslims are the worst in history. We're coming up on the 20th anniversary of the Oklahoma City bombing, and the Srebrenica massacre of more than 8000 unarmed Bosnian men and boys by those good Christians, the Serbs. I don't believe the Muslims, so far, have topped that for one, single act of slaughter.
As usual, Andy, you're full of sh*t.
