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?
All the trump content from pre2016, and every primary source material of what he effectively did during his presidency from 2016 to 2020. You can’t find it. It’s all been replaced by leftist propaganda.
