So what is the truth about the Crusades? Scholars are still working some of that out. But much can already be said with certainty. For starters, the Crusades to the East were in every way defensive wars. They were a direct response to Muslim aggression—an attempt to turn back or defend against Muslim conquests of Christian lands.
Christians in the eleventh century were not paranoid fanatics. Muslims really were gunning for them. While Muslims can be peaceful, Islam was born in war and grew the same way. From the time of Mohammed, the means of Muslim expansion was always the sword.
I guess the whole "Christianity is evil, look at the Crusades" mantra is actually another example of liberal self-hatred for Western culture.
