Well yes, becoming ethnically-centered is more recent because the conditions of the nations are observably in fast decline. The whispering phase was happening in the 1990's really, and you had the militia movements in the USA who were basically predicting what we have now.
The OKC bombing, Waco, and Ruby Ridge broke the momentum of that small movement, and made it so most people wouldn't even speak-out against the feds shooting a man's family, burning a compound full of cultists, or burning Masters alive on Whidby Island.
OKC is like the original 9/11, and reeks of false flag.
McVeigh maintained even in prison that he did what he did in service of his nation for the US military intelligence, and swore he would leave prison alive.
There was a reporter who claimed she could see him still breathing when they took him out of the lethal injection chamber.
But today, there's a total reversal. It's going more and more mainstream. Charlie Kirk himself, Trump, and many "right-wing" speakers/pundits are actually pulled more extreme by their audiences rather than pushing the audience further.

And yes, most people are against the abuse of children and blackmailing of politicians.
Trump's heel-turn on Epstein drew heavy ire from his supporters because it was blatant and dismissive.
And there's still an attempt to blame it all on antisemitism, and associate it with the left.
But even that doesn't really matter because at the end of the day a lot of people still believe that Trump is a net-positive for the USA because the left are against simply enforcing the law and removing illegal immigrants. They wave foreign flags and attack the agents doing the job.
But the message is reaching the top that most Americans are against what Israel is doing.
Right now Trump is claiming we're going to oversee Israel exiting Gaza, but I can't see that actually happening. Israel likely knows this is their last hurrah controlling the USA unopposed, and I think they are going for broke. BB, like Zelensky, can't have the war end because they'll have to face criminal prosecution. So there's nothing I would put past them.

The real problem is we don't have a way to undo this in an official way. The left's officials are just as beholden, and they just oppose each other in theatrical ways. But the US govt has serious problems that they have no solution for. Both the UK and France(and Germany & Canada to some extent) are facing major dissent from the populace. All of the economies are faltering as well, and if UK or France default on their debt that means trillions in treasury bond holdings disappear from the already insolvent US budget.
Nothing causes riots and revolt like failing economies, and it's hard to guess how it plays out on this scale.
The USA also seems to be interested in toppling Venezuela for reasons I don't know.

The democrats are now pretending to want the release of the Epstein files while the republicans and Trump block that. That is all theater, and if they really wanted to use it against republicans they had the last 4 years to do it. It's all a charade.
But the left and right fundamentally see each other as a threat to their idea of a nation in much of the West, that's real.
