When this happened during the Bush years I saw a lot of the a same behavior. All these people shut right up when the economy crashed, they went and hid in their caves for a year or so until they pivoted towards hating the Black guy (Obama). The reason being they finally felt a bit of the pain. When the inevitable crash comes from this era, they will all go back into hiding for a while.
Unfortunately this behavior has been a part of a portion of the country for a long time and we will be dealing with these people for the rest of our lives. EU, Canada and the rest talk a big talk about making moves to disconnect from the US. It would be nice to have independent democracies that can take up the mantle if things here need time to correct themselves.
This next time it feels like those same people will hate more than just the Black guy. Many seem to be supremacists who hate all other races and want them deported as a whole - not just the president. The world’s richest person is posting bizarre and disturbing pro white memes daily. And many young GenZ males who follow certain voices on the right seem intent on keeping the flame of racism alive. I agree it will last our whole lives.
