I've been to the MAS youth center in Brooklyn and ran into a lot of thuggish behavior. Most of the people there are very nice (especially the devout ones) but since it's a community center and not solely a mosque, there are a bunch of ghetto kiRAB that hang out there... it's almost a gang. Obviously they act nice to the people that run the place, but they are total dicks to outsiders. From what I can tell they have a superiority complex (even when it comes to other mosques/muslims) and when you couple that with an inner city upbringing they think they don't have to take shit from anyone.
So to me, this story isn't very surprising. Also, Rye Playland is a shithole.
The generalizations you guys are making are pretty sad though... but I guess it's easier to go through life this way. Less thinking is required, ignorance is bliss, etc...
