Well, the vast majority of Muslims I’ve known have been perfectly nice people. BUT, the problem with Islam is that, unlike other religions, its crazy fringe isn’t just a fringe but a fairly large plurality. There’s a difference between a 0.01% fringe and a 10 or 20% fringe — the latter being more like a *slice* and big enough to cause big problems.
But if they are sincere believers, there are those really dangerous parts of Islam lurking in the background.
Most of the Muslim-Americans are hard-working folks and they're quiet about their faith (except for Tlaib and Omar).
But that's because they're only 1% of the population. They won't start to make noise until they reach 5%.
