Why do liberals support Islam?

This is a classic dilemma. Do we have to tollerate intolerance?
I think there's a world of difference between not attacking someone and defending them. I'm not very liberal by European standards but I probably would be in the US.
Now, I'm not a muslim, nor do I like any muslim state. Also I would never defend the actions of muslim killers or any killers for that matter.
However, I will also not judge anyone solely based on their religion. I know muslims who are very kind people and so far I haven't met a terrorist. If I'd judge everyone by what a few of their group have done, I couldn't be friends with ANYONE.
The point is, I try to accept people for who they are even if I think they are WRONG. Even if they hate women or they are vicious racists. Because if I don't meet them on eye level and if I don't engage in an open minded conversation I will never change them or might even make them worse.

Making us hate all muslims is EXACTLY what the terrorists want. More hatred means more extremism. More extremism means more willing recruits for terrorism.
