The same could be said for the gangs that roamed New Orleans after Katrina or the gangs that roam Detroit on Hell Night. Yes, there are a few who band together, but I wouldn't call that "united" in the sense that all Muslims were united for a single cause. Make no mistake, I'm not making excuses for them. I agree with your premise of there being a certain percentage of the population that are thugs, just not that they are all, 100%, are going to somehow unite to bring about the destruction of Israel.
