This is simply historically false.
Wow. No, it isn't "historically false," and it isn't simple in any way. Sorry.
I think SJWism is the extreme end of the "personal liberty ideology" , as the slight taking and perception of restriction or regulation is constantly expanded (or ratcheted). You can't disapprove/ignore, you must approve.
There are certainly elements of individualist ideology in SJWism; but in many ways, what Donald Trump advocates is also an extreme of individualist ideology.
That's what I assumed the answer was, but was hoping for something more logical to come out of this.
I don't think you can approach it in a "logical" way; attempting to impose a logic onto it has been the thrust of imperialist thought for centuries now (I'm not calling you "imperialist," I'm simply saying that logic has a history, and it's a very Western history). Logic assumes that you can reduce the situation down to a simple equation, but there's no equation, rhyme or reason, underneath it. All you can do is try and observe everything, as best as you can, and go from there; but the conditions will always shift on you. There isn't anything logical to the argument, it's an argument about historical circumstances and how the West was won, and how people are reacting to that now, in the age of information (or misinformation, both work). You mentioned context above, but this is context - history, culture, this is context. Context doesn't end at "Halloween costume."
Some people would have us ignore narrative altogether because it's misleading and erroneous; but these people overlook the possibility that the impulse to overlook narrative is, quite simply, a part of the narrative itself.
EDIT: not to be harsh, but when most of you (and Dak does this a lot) try and assess the entire situation (i.e. the controversies of identity and identity politics across the board), you take it as though it exists
in toto in every given situation - so you can apply logic and calculation to it and come up with numerous ways in which the argument is false or misguided. But there is no situation in which all the conditions are manifest, you have to account for history and other factors. This is the way that "context" works; you can't just reduce every situation to the given conditions of its immediate context, especially when discussing these issues.
My personal opinion.
