Despite it's getting so much bad press these days, due not a little bit to ignoramuses defaming my faith by claiming their "identifying" with it justifies the most evil, reprehensible behavior imaginable, fundamentalist is really a "null" word--adhering to a set of principles isn't necessarily, or even usually, a bad thing.  "Do unto others as ye would be done by" is a fundamental principal.  So is "al ʿamr bil maʿrūf wa-in nahi ʿan al-munkar"--demanding right and opposing wrong.

Reality is that the current idol of the Christian right arrogantly and cavalierly violates Christian principals at nearly every turn.  He is anything BUT a fundamentalist.  He eschews humility for hubris.  Breaking promises and lying violated both Christianity and Islam.

If anything he deifies his own desires.  And the Christian right, whether they admit it or not, deify him as the man who will save them from "scary foreigners".

"If such are the priests, God help the congregation." (old Arab proverb)
