"Getting old" no but alzheimers and other dementia this is actually a gross over-simplification; they definitely CAN come along with a "tourettes-like" compulsion to say the most inappropriate thing. It doesn't mean that person was secretly racist when they were younger, it's literally a thought process of "what would be the worst thing someone could say right now" and that actually being verbalised.

Again, of course, none of this actually happened but I guess that's the problem. Fictional viral videos generating a tidal wave of un-nuanced outrage-opinion based on little to nothing at all and everyone feeding off each other to generate whole belief sets based on layperson opinion instead of actual knowledge and understanding. 2020 innit.
