For anyone who still thinks that Islam is one of the world's "great religions", they should spend some time at that BB and become re-educated as to what it really is: a socio-political system that controls every aspect of a mindless peoples' life, much the way fascism, nazism and communism did.
Great religion, my butt. Islam, The Cult of Horror™.
Additionally it would probably only take one beheading video. Having seen them all I would suggest the most recent. There is no doubt when you watch these that these people are sick beyond sick. To do what they do with such calm, glib facades, and then praise their god as they do it, truly reveals them as a death cult. The true horror is not so much what they are doing, but the manner in which they do it.
