The American Thinker has an excellent article entitled "Jews Who Won't Support Their Allies" which discusses Jewish "tolerance" for Muslim intolerance. The article is spot on target, and the comments others have made are very worthwhile reading.
One of those comments says:
"If we extend unlimited tolerance even to those who are intolerant, if we are not willing to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them... We should therefore claim in the name of tolerance the right not to tolerate the intolerant."
-Sir Karl Hopper
For the record, I don't know if the attribution is correct. Perhaps it was intended to be attributed to Sir Karl Popper? At any rate, whoever said it, it's אמת -- emes -- deep truth.
America, you have been warned.
