sectarianism of Syrian rebels

I have no doubts about the sectarianism of Syrian rebels and their supporters.  It is quite open on Facebook pages.  But nothing, NOTHING, that Robert Fisk says on any matter has any credibility.  The man has lost his marbles and more.  Look at this:  "But sectarianism is biting into the Syrian revolution. At the end of last week, one Syrian told me that "they are bayoneting people in the villages around Damascus"."  Who is carrying bayonets in Syria?  Is Fisk confused?  I disagree with Fisk even I agree with him.
