It's a word you use when you want to signal to everyone that you'd like to cease having a polite discussion and turn it into a battle of ideologues, very commonly initiated by those who lack introspective processes that fuel the political narrative that they pretend to demonstrate against.

When someone's inner monologue is so full of derisive irrationality that buzzwords pushed with an agenda are the first "opinions" they share, its somewhat of a moot point to engage with them as the point of their post wasn't about having a civil discussion. I generally consider it an indirect act of kindness when people like this immediately show their cards, because it's pretty easy to spot and ignore (if the loud sound of their mouth breathing doesn't already give it away).

Overly zealous or performative adherence to progressive and liberal values, where individuals or groups are perceived as seeking out instances of offense or injustice, often in contexts where such issues are viewed as minor, exaggerated or misinterpreted

I disagree…once upon a time it used to be a pretty funny site full of pop culture oriented comedy without much political undercurrent. Then something happened seemingly overnight perhaps 4-5 years ago where every other article was a listicle with a preachy lefty bend to it. Within a month I pulled it off my RSS reader but would periodically go back to see if it was interesting and funny again. After a while I stopped visiting and wrote it off as yet another casualty of the new Puritanism.
