A good rule of thumb to keep in mind.
The so-called "radical-extremist" Muslim is the one cutting off your kid's head, the moderate ones are watching with glee with their children.>
It's not much more complicated than that.
When directly confronted with irrefutable evidence of Muslim misdeed, they will invariably weakly condemn it and
ALWAYS send out some signal that the whole problem stems from others’ bias against them. They are ALL traitors and maniacs IMO.
