We're all used to the obvious rot and see it every day; Advil's Black Pain Equity campaign, pronoun sections on corporate meeting software, "safe injection sites" funded by municipal governments being a hot bed for drug abuse. That stuff is so brazen that anybody with a brain and without an agenda will be repelled immediately.
But what about the subtle rot? I'll use the Onion as an example. Perhaps its a bad example since they are a good showing of obvious rot, but I just learned that they purged their old African-American neighborhood terrorized by ask murderer headline and it happened with no fanfare at all. A slow purging of old material deemed ungood; a memory holing except for the fact that the Onion used to be printed on paper and people just took pictures of the old headline. But the point stands -- I had no idea it was purged until I deliberately went looking for it, and its the only old "edgy" Onion headline that appears to have been purged in this fashion.
What else have others observed?
People that think tropes = bad, having nothing to say when the race/ gender of the parties involved in the trope swap or otherwise change.
White Men being pigeonholed into joke characters (NOT comedic relief characters) or villains
Refusal to allow non-white or women characters to overcome any legitimate hardship
Offensive comedy only allowed to be offensive in one direction
Increasingly passive-aggressive language being used by companies and organizations
Industries turning from apathetic to outright antagonistic and hostile towards their customer base.
Videogames don't cause violence but do cause these other activities
Recent Spiderman game did this. Players complained about the Mary Jane sections (because they want to play as Spiderman in a Spiderman game, duh); and so the sequel had Mary Jane sections again where she was even more overpowered.
This sort of thing keeps getting more brazen to the point that even normalfags are calling it out. Even on Reddit I see posts making fun of Mary Jane being a stupidly overpowered character.
Also recently we have the Fallout show where the creators have made it very clear that they're out to push propaganda and NOT please the fans.
Claimed that it was impossible. Just didn't say why it would be impossible: ESG and Amazon.
