I don’t know if this article is describing this phenomenon accurately, as the first paragraph contains an obvious falsehood: “ A flyer with an image of a gun and text reading “shut the fuck up, terf” (trans-exclusionary radical feminist, a slur) was circulating. ”. TERF isn’t a slur. No one has successfully beaten and killed a woman while calling her a TERF and then got away with it in court like the gay panic defens…
A slur is an allegation that is likely to insult them or damage their reputation. That's clearly why terf was used in this context. I've noticed leftist communities frequently attempting to redefine incendiary words (such as 'racism') as a political tactic, to a lot of success.
These are federally subsidized academic fields
So if you want to see the Left stop redefining words, the public needs to stop funding their careers in academia
