Certainly.. It is best to only refer to experts such as Robert Spencer, Glenn Beck et al for their expertise on such matters...
Well, I did refer to your linked statistics, above. Are you then collaborating with Spencer or Beck?
If you're talking about the fact of conservative movements in Islamic belief, this really can really be denied. It would be like saying there was no such thing as conservative political belief in the US. Surely you're not denying the existence of demography?
Meanwhile, a white supremacist has attempted to assassinate the President and two other representatives by sending them ricin in the mail... And he barely rates a mention in the news. Why do you think that is?
Well, for one thing, ricin is considerably less explosive than actual explosives. In fact, there are a number of reasons why it gets more coverage: terrorism against common citizens, an attack on a marathon, for fuck's sake, whereas poison attacks on American politicians has been tried before, and on a much larger scale. It's also less sexy because the ricin mailer went after both Obama and a white Republican senator. Doesn't really fit into an exciting narrative. And, lastly, they just arrested the guy two days ago. How do you know he's a white supremacist? If so, why did he try to kill a white Republican senator? Do you have a link?
