I'm sure they did at the time this (SJW) acronym got popular. That was maybe 10-15 years ago.

SWJ wasn’t a popular acronym 10 years (let alone 15) ago in the online communities I hung around in. ;)

		Sure, I get that. But the term gained popularity in 2012 it seems, according to google trends. https://trends.google.com/trends/explore?date=all&q=SJW&hl=e... And there's a entry from 2011 in urbandictionary.com, so maybe that's around when it was coined.
