Compare the number of terrorists to the number of Muslims. It's a tiny percentage.
The real problem is that the terrorists operate with near impunity in Muslim communities. While they may be rejected they aren't reported.

One cannot argue with one who is so blind that sees the world through rose coloured glasses. Perhaps you should do a detour while overseas and stop off in Israel for a week or so to see first hand what islamic terrorism is all about!!
What evidence would this detour provide to support your incorrect assertion that "nearly all terrorists are Muslims"?
Where is there a substantial non-Muslim terrorist movement?
The only things that even come close are drug-war related.
