I would not single out Islam. Each belief has its "extremist"
side...look at the history of Belfast for most of the middle 20th
century...or the persons currently burning churches in parts of the
deep South in the US... or parts of Utah.....or parts of the Middle
East. I would rather you nominate ALL the right/left/holier than
thou/"my way of the die way"/ etc proponents no matter WHAT belief they
profess to belong to.
