The US population is just struggling too much to care, that's part of the playbook: keep people poor and the rich rich, so that the economy will be the main driver of votes, and of course the sitting party is always to blame for the bad (or perceived bad) economy, so people vote for the other party no matter what. The same thing is brewing in east germany with AfD stemming basically from the same economic problems, and you'd think they know a thing or two about fascism there.

As horrifying as it is, wars are good for the economy because governments are printing money like they're no tomorrow to build weapons and ammunition, it creates tons of jobs. It'll come at the cost of a depression when tomorrow finally comes, but that'll be the next party's problem, and people on average can't see much further than the tip of their nose. Then they'll vote the fascists back in to "fix" the economy again, just in time for the economy to start turning and take credit from the previous administration's policies. People don't want progress because progress involves compromises while they're hurting right now, they don't want to compromise for the right thing.

Nobody would care about trans people, immigrants, green energy, electric cars, etc if the lower middle class was wealthy. People care because of the perception it's taking away things from them in a time of need where they can't afford it. For trans people that's DEI being perceived as favoring against them, for green energy that's going the more expensive route they can't afford/it's cheaper to set their trucks to run coal and not have to put AdBlue in or replace a clogged up DPF. They want regulations gone not because they don't care about the environment, but because they hurting right now financially and it's costing them right now.
