Well, many people like to point out that Islam is a peaceful religion, but the fact of the matter is that it currently has a high proportion of anti-Jewish, anti-Western nutcases who spew hatred. There is also this idea that
any region of the world which was once controlled by Muslims belongs to Islam by divine right, thus explaining the numerous Islamist insurgencies. Islam has a huge house-cleaning job to do before it can seriously be considered part of the civilized world.
There are peaceful Muslims, but they are unfortunately not the ones controlling the influential institutions of Islamic thought.
Sounds like we need to thin the herd some.
