Respectfully, I think you and I might have different standards for what constitutes an SJW.
The spots I come from, I've personally seen "SJWs" commit illegal actions like doxing, forming cyber mobs, trying to get people fired from work, forming professional blacklists, swatting, pushing people to the edge of suicide, promotion of segregation, using slurs against anyone (especially members of underrepresented groups) who disagrees, advocating violence, exploiting those suffering mental illness, committing acts of assault, committing acts of vandalism, going on smear campaigns, looking for acceptable targets for aggression, the list goes on. And all of the things I've mentioned? People will do it over fictional stories to innocent people.
I don't say any of these things lightly, in exaggeration, or without having a huge collection of specific examples to back them up. There's not a trick or a catch where the victims were secretly monsters to warrant the abuse they received. I understand very well how these people went from well-intentioned activism and got twisted into bigots and criminals themselves and I know why they think they're morally in the right for their behavior. It's an ongoing issue and has been for several years. Some of the incidents I mentioned are actually going to court thank god. Being here, I'm currently working to recover from being frankly pretty traumatized by what I've witnessed. The number of people participating in this behavior, where I'm coming from, is alarmingly high too.
I know people misuse both words, but for me personally (and I'm both a woman and a less-visible minority, for what it's worth) I seriously put similar weight on the term SJW as I'd put on neo-nazi. I've had situations where I've been walking down the street and had to honestly ask myself which extremist faction would pose a bigger personal threat. Sometimes there are people who use "activist" as interchangeable with SJW, but honestly I have no problem with regular activists. A lot of my stances could be classed as traditionally liberal, and I'm someone who likes to actively seek out new perspectives in media too. But condemning the abuses I listed above, that alone can make you a target with these people.
I have not seen anyone in FFXIV so far who would constitute an honest-to-god SJW as I know them. I've seen people falsely accuse others of being SJWs, and when that happens I try to point out that they're being ridiculous. I have seen a few people here who are honestly bigoted (mainly targeting Koreans, which I seriously wish they wouldn't) and do know what you mean about people targeting the groups you mentioned. Those things are problems too. In my experience though, the right-leaning identitarianism tends to be (usually) more casual/superficial and limited to a few jerks. Left-leaning identitarianism as I've encountered it is more about systematically destroying people en masse while creating social hierarchies based on what group you're born into.
For the record. The fact that we can have this conversation without accusing each other of stuff and without serious walking on eggshells to me says you wouldn't be an SJW in my book. It's possible to be socially critical and think there's room to improve things without being part of that ideology.
This background is why I'm inclined to hear OP out more too. In other communities it would be extremely likely that they did nothing any reasonable person would find objectionable but had been targeted regardless... often with staff endorsement. My saying that I'm inclined to be more sympathetic to the GMs overall is a really big deal for me with all of this. Any time I say stuff in defense of SE and their staff, it's in light of them being unbelievably kind and professional particularly compared to what I've encountered before.
