Interesting that you asked about "SJW". I had many acquaintances that used that acronym. Sometimes followed by "Snowflake" or "Cupcake".
Not wanting to appear as if I was not "up with the latest" ... I never asked ...
Finally, I did ask my brother ... figuring, as he's a PhD, MD and teaches the young'uns at a medical school ... he would know ...
He laughed and told me, surprised that I was not familiar ....
He started out with it being the reason that he can no longer use the term, "Old Wives Tale" ... and now says, "Old Husband's Tale", but even that offends some of the LGBTQ (followed by a bunch of other letters) community.
So, continuing with my normal bent of making short stories exceedingly long ...
