I dont know a whole lot about /pol/ or 4chan other than occasionally they can be good at exposing stuff the media wouldnt touch with a hundred foot poll. Apparently they were too good at it, because the place now seems to be overrun with shills and trolls trying to discredit and destroy it. This is most likely an example of that.

Sure you do have some mentally ill anti social kids that are attracted to the place, but this sounds like JIDF/Jewish trolling due to its similarity to something Al Queda or Isis would think, as Jews have long been attempting to link Islamic extremists with right wing dissidents/Jewish critics in the public imagination.
