That is correct. I don't live in your world but I did spend some time growing up there including at one point a spot not too far from where you grew up just outside the mouth of Little Cottonwood Canyon. I've lived in big cites, residential suburbs, and small towns, in rich areas and extremely poor ones. I spent some of my time growing up in schools that were almost totally white, a school that was designated the most ethnically mixed school in the nation, and as an expat in a true authoritarian nation in a very unwhite part of the world where I went to the equivalent of elementary school. I've lived in these places, not just visited, but lived. Where I choose to live now is an area that is either minority-majority or straight up majority Hispanic depending on where you are drawing the boundaries.
It is weird to me when you talk about massive groups of people as if they are a single cartoon character who has decided to go by they/them pronouns. I also wonder if news penetrates at all the bubble constructed around some of the people here, occasionally you included. I obviously recognize your tired "demographics is destiny" argument that was popular 10 years ago, but actual history has happened since then. When Glenn Youngkin beat Terry AcAuliffe to become Virginia governor, the Hispanic population was the most likely to vote for Youngkin. Florida has gone from a perpetual swing state where hanging chads made the difference, to one that is safely conservative thanks almost entirely to the Hispanic population there. Texas too is now only conservative because of the Hispanic population after white tax refugees from California strengthened the leftist voting block. Texas just had a district that had never been won by Republicans ever in history, one that is 85% Hispanic, flip to Republican. Even in California in the heavily Hispanic California Central Valley, it is solid red.
I have heard variations of your same "the political right is white supremacist and can't handle the browning of America" from LogGrad, FishOnJazz, JazzGal, Thriller and many others. Even left-leaning outlets like CNN and MSNBC have been airing segments noting the erosion of support among minority voters for the Democrats. It isn't 2008. The whole idea of the they/them melaninated American cartoon character in your head being unswayed by the train wreck the Democrats have caused does not say good things about those who continue to voice that obviously false idea.
Here is a reality check: Currently Joe Biden has lower approval on his handling of the economy than did Jimmy Carter at this same point of his presidency. A sizable chunk of those people who disapprove of Joe Biden's handling of the economy have brown skin. Deal with it. The damage being done to the democrat brand by the obviously-in-decline Joe Biden and the choices made by this democrat controlled house are going to have a long lasting electoral impact.
