Nosy neighbor became A Karen.
Being a trans ally/educator became groomer in some conservative circles.
Liberal became libtard.
In the past weeks, most modifiers used to discuss Israel/Palestine have intensified, not softened. (Wasn't there some Israeli official who used the term "subhuman" on Twitter?)
Mask became chin diaper!
Military/militia wannabes became Meal Team Six / Gravy Seal
Interpersonal conflicts, political debates, and misunderstandings have become accusations of gaslighting-- i.e., two people accusing each other of attempting to brainwash the other
I'd even argue that useful idiot becoming NPC is a change to something more extreme. (The idiot is implied to be unwitting/naive while the NPC is implied to lack agency.)

And thanks to the vague definition and pretentious borrowing of a term from statistics it is virtually guaranteed to be overused and misunderstood in political discussions, fueling disrespect, anger, outrage, and preventing sober, productive reflection.
There must be thousands of these, fueled mostly by social media.
As for soft language-- since anxiety/depression levels have gone through the roof over the past two decades, there's been a trend of soft language becoming reified and relegated to ASMR videos. As a strong and vocal supported of narrowing the dynamic range of mainstream audio, I whole-heartedly support and endorse this trend.
