Guess what happened to quality around the time all the DEI stuff started shooting up in popularity around a decade ago? Everyone sees it. Everyone experiences it. No one wanted to talk about it, until things reached a breaking point.
You're going to have to make a much better argument of connecting the dots if you're going to blame the enshittification of everything on... Black people and women.
None of you folks are ever 'afraid of talking about it', because any time this subject comes up, we see a full broadsides of tenuous, frequently mask-off racist nonsense.
Meanwhile, the champions leading the fight against the DEI boogieman have a truly amazing knack for both being, and appointing some of the most ignorant, least qualified individuals to ever hold positions of power... And are now speed-running their way through breaking everything.
