I thought SJW meant a combination of 2 and 4? I'd call #1 activists, not SJWs.
SJW means whatever the person using it wants it to mean. It's not so much a specific thing as a generic pejorative, these days. It's not spent much time since it was coined being anything else, really.
Though, to that latest post, I don't think I'd agree that the term's overused. It's more that some very vocal and persistent people are trying to paint the term as muddied, for their own purposes (generally to deny it exists, for varying reasons). I don't see it misused very often, particularly in anything widely seen or read. I see it
called misused significantly more, heh.
... also I have no idea how you picked up the W in SJW meaning worker, heh. Conflation with social workers, which is something very, very different?
I think I might've misinterpreted you here a bit, sorry. I blame English being my second language I interpreted your meaning as that labeling is still necessary in order to tell right from wrong (and again, please forgive me if I am putting words into your mouth here).
If so, I was referring to labeling of other people, specifically for the purpose of othering, which is most often harmful. Being able to identify unwanted stuff is important and a good thing, dismissing people as "the other" is not.
Not so much othering as identifying people as actually doing bad things, what's generally referred to as being bad people. One of the biggest fights civil rights has had (still has) over the years was (is) getting people to actually call racism, racism and racists, racists -- same with feminism et al and misogyny. Instead of just the way things are, the way god intended, etc., so forth, so on. Not just an opinion but a discrete set of stuff that's being done. It
is, to a degree, othering, though.
And while it is often harmful, it also serves a pretty important purpose. It's
incredibly hard to recognize and change behavior if you don't see it unusual, if you're not being set apart from your peers when it enact them. It's as much needed as it is to be watched carefully.
