Really? I honestly didn't think the term existed prior to a few years ago. But regardless of its original intent, the term "SJW" has been bastardized by groups such as Gamergate to belittle anyone who wants any sort of social or progressive change in video games. Va11-hall-a was made when Gamergate was still going on, they really should have known better than to adopt a term that had become a calling card for such an abusive group.
edit: Wikipedia reinforces this:
GG turned the term "SJW" into an insult to mock anyone remotely liberal.
Wikipedia is not really a gold standard here. Again, the term has been around since the 90's. Internet culture may have given rise to it again, but it did not originate from the internet nor memes. I heard it back when I was in middle school in the 90's.
And GG is not the best example, cause again, out in the world... eh? I can go around my office right now (made up of mostly young people and I can guarantee you maybe two person will know what GamerGate is. Nothing is bastardized because the source is meaningless in the end. Maybe to you it is, but that is not the practical case. And no, they should not have known better. That's tone policing. To you it may mean that, but it does not mean that to someone else. Your feelings are fair on it, but don't expect that your own feeling on it will apply to everyone nor that will it is the de facto meaning. Most people, especially outside of gaming use the term with zero relation to changes in video games. And in gaming, outside of this forum and some sites (which can be very insular), it is still used more often than not to have a laugh at people who are are just bonkers. Now just because GG bastardized the term to complain about progressive developers, does not mean they own it; because GG would have to actually matter for that to happen and they don't matter.
So we will have to agree to disagree.
Ah right, here in the UK the term "PC (Political Correctness) Brigade" is an analogous term that's been around since the 90s at least, I guess your term sort of superseded it once it spread across the internet.
At the end of the day, both conservatives and liberals are mock worthy when they behave in ridiculous or counterproductive fashions. My father, who is now retired, did civil law and was heavily involved in activism and social justice, but he would always say that there were segments of progressives who would do more harm than good because they lacked maturity, perspective and actual real world experience beyond their bubble.
