These organisations are dangerous and some of them are pretty wealthy..
There's a bunch of them in NYC, and one close my home. There's a bigass mosque with a private parking lot, and the Imam drives a Mercedes and Lexus.. They litter telephone poles with fliers with messages of conversion written in english. Looks harmless, but anyone who knows the truth also knows how dangerous these people can be. It's mostly pakis, but also some africans and arabs. They go around asking muslim owned businesses for donations and people always give, atleast to my knowledge.
