What if there was no George Floyd but COVID or vise versa?
The two are related. Without COVID, you wouldn't have tens of millions of Americans sitting idle, binging 16 hours of cable news/social media every day, not able to go out and do the things that normally keep them occupied (i.e., work, school, church, gym, visiting family, going to restaurants/bars, etc.) That sort of society-wide lethargy is a powder keg for unrest. The George Floyd protests were so huge mostly
because of the COVID lockdowns.
COVID was the most animating event of the past twenty years, and it wasn't even a singular event - it was (and is continuing) to get rehashed day-in-and-day-out by a rent-seeking public health intelligentsia helped by their friends in a profit-maximizing media industry. You can't separate anything that has happened since March 2020 from its omnipresence.
