They represent SJWs in the mind of
Sargon of Akkad (real name: Carl Benjamin), an anti-progressive, anti-feminist YouTube celebrity who greatest fame came during the height of the Gamergate controversy when he relentlessly harassed and attacked women who dared complain about being harassed and attacked by guys like him. He's probably done more to promote the Gamergater use of SJW as a pejorative than anyone else, so I suppose that makes him an authority of sorts.
Would I be wrong to call them SJW?
If they are SJW, then the criticisms of SJW are actually valid. If they aren't, then when will the real SJWs tell them to bugger off?
That video is nothing but a collection of tiny snippets of dialog, discourse, and argument. It's impossible to understand the point each speaker is making because we aren't given enough of their words to discern it. We get dropped into the middle of arguments with no knowledge of what started it, or who, or why. In fact, in most cases we aren't even getting complete sentences, just fragments.
So I don't think real SJWs would tell them to bugger off just yet. IMO, real SJWs would know better than to take Sargon of Akkad's YouTube videos at face value, especially one that looks like a mishmash of soundbites spackled into a wall of propaganda. They would be far more likely to try to come to a better understanding of each person's point of view before deciding how to respond.
