Your mileage may vary but at least around the chuckfucks at work who used to try to laugh it off Kamala-style every time I criticize the current regime back in 2021 now either desperately try to change the subject or run off quietly. None of these people try to defend Biden and his bullshit, hell they don't even mention his name. For people who whined about Trump so much it's clear that their heart is not in it anymore. With every ever-growing grocery bill, gas pump fill-up, or utility bill their smugness has evaporated so quickly.
Looks like demoralization works both ways.
I think that he has a point in that if they are allowed to just act like the past two years never happened and they didn't play a major role in it they won't have learned their lesson enough to not fall into the same trap again.
