Sectarian methods and ploys of the Syrian armed opposition

There are many scandals regarding Western media coverage of Syria, which solely relies on the statements and claims of Syrian armed opposition groups.  But one of the most glaring omissions in coverage is the level of sectarianism by those armed groups:  it is not a question of claim because the evidence of its sectarianism is quite abundance: from blatant sectarian threats and declarations, to sectarian kidnappings, to sectarian shelling and indiscriminate bombing of certain neighborhoods that has a certain sectarian preponderance, to the subservience to the sectarian regimes of the Gulf region, to the sectarian massacre and sectarian cleansing campaigns.  I mean, what else do you need before you start writing about the sectarianism not only of the Bin Ladenite groups but of the "moderate" and "secular" Fee Syrian Army and its variants?
