Here's the thing: where are the Christian extremists to rival these people? And don't say that a couple dozen abortion-related acts of violence over a few decades compares to the sheer scale of Islamic Jihad.
One could argue that Christian extremists are to Muslim extremists as White Collar bankers are to gang bangers... A whole different scale and different methodologies.
More education is needed by EVERYONE, with a HUGE side of your ideas aren't the only ones out there. The more people know about any religion the less the crazies will be able to use selective preaching to bend opinions.
Of all the things in the world, it seems allowance of others beliefs/life styles (general put your self in others shoes) is lacking and the cause of most crap out there.
