The crusaders killed women and children.

To defend their culture from being erased, Christian Kingdoms had to recruit everyone they can. It's only natural that some of their recruits turned out to be bad people. If Muslims don't like the fruits of war, they shouldn't start one.

Muslim conquest wasn't a purge of everything non-muslim like the barbaric crusades was.

Before Islam, their current territory used to be the Eurasian center of knowledge with many diverse cultures. Are you trying to tell me that all these knowledge centers and cultures had been just magically erased by their God? Leave this idiocy for the believers, Muslims absolutely had purged them.

muslims don't actually practice all that dumb shit

Even Google can find some recent executions for you. The execution of that teacher in France was celebrated by many moderate Muslims on social media. Killing is an important part of their religion. In their lands, it's so common no one even bothers caring anymore.

christians don't stone people to death

Stone? Christians are known for burning heretics and forgiving everyone else. They aren't Jews.

Muslims have been much more tolerant of christians and jews than those religions have been tolerant of islam

Muslims let others live in their lands, but oppress and periodically attack them. Christians used to let Muslims live in their lands, didn't oppress, but still periodically attacked them. Christians appear to be slightly better here. Jews, they have been at war with Muslims since the foundation of Israel, so it's hard to know their inherent tolerance.

Did you really think it was muslims that did 9/11?

The executors, most probably, were Muslims.
