Yeah, well, everybody can look up himself or herself who pretended to have authority to clarify what's correct and what's not, and I don't think I'm alone when I consider this an attempt to dictate how others have to call the group. Meanwhile, there's no way you can claim I "projected" without showing me trying to at least delegitimize others' choice of words.

Did we have
this already?
Syria really is a mess.
Everyone who bombs Da'esh helps Al-Nusra if I'm not mistaken (they still do feud, don't they?) and of course FSA, Assad and Hezbollah.
Everyone who bombs FSA helps Assad, Al-Nusra, Da'esh and kinda Hezbollah.
Everyone who bombs Al-Nusra helps Da'esh, Assad, Hezbollah and possibly FSA.
Everyone who bombs Assad - wait, nobody does.
Just about nobody seems to like more than one faction, so everybody who bombs anyone does as a by-product help a faction which he loathes.
Concerning air power strategy:
The U.S./Saudi approach appears to be to first and foremost seek to hurt one faction (Da'esh), not to help a faction 'win' and end this war.
The Russian approach appears to be the opposite; maybe they don't really intend to help Assad 'win' this, but they don't hate the FSA rebels as much as the jihadists, and still focus on the FSA apparently. This means they're in the fight first and foremost to help a faction.
(I don't think they take this seriously as a munition proving, tactics development or crew training ground, though it might be 90% meant to bolster Russia s a great power or to break the stalemate in Eastern Europe by making themselves indispensable for the solution of the Syrian knot).
The Russians seem to have more luck in generating proxies, even if they need to invent them out of hot air (as in Eastern Ukraine). The U.S: hasn't found good proxies in Afghanistan, Libya or Syria.
Personally, I'd at this point prefer if Assad prevails and lets the Kurds have their de facto autonomy as did Saddam post-1991. A victory of the more likeable elements of the FSA is at best very distant in the future at this point, and the war apparently is worse than Assad's dictatorship was. Even a Bosnification with a perpetuated division is unlikely, since a perpetuated control of much terrain by Da'esh or Al-Nusra seems intolerable to the U.S., Saudi-Arabia, UK and likely even Russia.

P.S.: BTW, why does the Washington Post use a map that draws Israel's and Syria's borders as if Israel's had annexed the Golan heights for real? AFAIK no such thing was ever recognised by the UNSC or U.S..
