You can find examples, but they are very few and far in between.
For crying out loud, do you remember a couple of months ago when they wanted a Jhihad against Burger King because the picture of an ice-cream cone SORT OF looked like the symbol for allah if you turned it sideways and reversed it. I'm sure there are good Muslims some where, but they sure aren't letting their voices be heard.
Well, I DID say "few and far in between" didn't I? :-)
Look at it this way. If you're a "moderate muslim" and you speak out against the hijacking of your religion, what do you get? You get to be a target.
However, if you just mind you own business and shut up...Well, either the terrorists win ("Hey, you can't kill me, I'm muslim like you.") or the terrorists lose ("Hey, I'm not one of THOSE guys. I'm with the religion of peace.)
So, where's the incentive to speak up?
