Oh God, not those chicks again. Somehow you always forget to include the wahabbist head choppers including AQ. SDF is basically every jihadi rebel besides ISIS, plus those kurd chicks.

Here is where SDF ambushed a Marine and shot him at a firebase.
SDF is simply another bunch of brutal mideast murderers. They just happen to serve the neocon purpose and perpetuate the farce that some Syrian rebels are good.
There are literally thousands of those those chicks, who have been engaging in firefights with the real jihadis for years. The YPG (the male units) and YPJ have been the effective force that has defeated ISIS on the ground in the yellow areas of the Syrian map.
They know the jihadi headchopper type well, and they are directly opposed to them.
I hope you know that SouthFront is a Russian propaganda outlet (Syria is to the South of Russia - their Southern Front). They actively try to divide their enemies with disinformation.
So thousands of people (10s of thousands in total) fight and defeat ISIS over several years of grueling combat, but you dismiss that as proving their anti-jihadi credentials. On the other hand, Russians allege a single incident (that the US Government denies), and you accept that to damn them all.
It seems that you might have confused the SDF with the FSA (Free Syrian Army), which the USA used to support under Obama, which did include lots of re-fried jihadis, from a witches brew of groups.
They are now concentrated in the NorthWest of Syria (Idlib, Afrin and al Bab), and Turkey is trying to form them into a more professional looking semblance of an army, which they apparently plan to call the “National Army”. Maybe they plan to soon declare independence from Syria, to join Turkey.
Are there any other kind?
