What Islamic "radicalization" means

[...]

But those who are "radicalized" -- and these are a great many -- have not embraced a doctrine that has nothing to do with Islam, but rather has everything to do with it. The texts they read are the same. But they read the full texts. They know the duty of Muslims. They choose, however, as their instrument of Jihad not only such things as campaigns of Da'wa, and the careful Tu-Quoque-and-Taqiyya efforts designed to prevent Infidels from finding out just a little too much about Islam, mainly by keeping those tiny Infidel minds busy with "the three abrahamic faiths" and "we revere Jesus and Moses" and of course the five canonical prayers, and the giving of zakat -- for fellow Muslims -- and the observance of Ramadan and the inspirational delights of the hajj, but also violence. And that is what "radicalization" means -- not some different, weird, unrelated set of beliefs, but merely the set of beliefs that arise naturally out of, indeed are inculcated by, Islamic texts read and understood as Muslims have read and understood those immutable texts for 1300 -- or possibly 1200 -- years (for it is unclear when the Qur'anic text was fixed in amber).
