I and my brother were once suddenly accused of doing something -- I am not sure what it even was -- once at school by other classmates. These were not Muslims or any other alien group, but regular Americans. We did not get stoned, but just attacked verbally. So I don't think this sort of thing is confined to some "other" hated group. I suspect someone was trying to shift blame onto us, as we were not totally regulars in town, to cover their own misdeeds. But I never knew what the cause was, or what "crime" we were supposed to have committed.
