OK, I've rested and I CAN now. I am prepared to explain why you are a moron.
Even in a highly diverse society, due to differing social habits, there are still going to be areas of life which are going to be remain disproportionately white. Even if the United States became 90% POC, rodeos are still going to be overwhelming white. That would not be a sign of white dominance. It is just a sign that other groups have little interest in rodeos.
Mexican dominance in mariachi music is not a sign of Mexican cultural dominance. It just means that Mexicans are the only people who care about mariachi music.
This point is particularly stupid. Trade Unions have been in decline for decades BECAUSE only white people care about them.
Corporations deliberately use mass migration to break up unions and to undermine working class solidarity. It's hard for workers to organize among themselves when they don't even speak the same language.
There was recently a leaked Amazon memo that completely gave the game away:
"Whole Foods employs roughly 95,000 people nationwide. Data collected in the heat map suggest that stores with low racial and ethnic diversity, especially those located in poor communities, are more likely to unionize. That’s a lot to unpack about your favorite place to buy expensive organic pasta sauce. When a Whole Foods suddenly pops up in a low-income neighborhood, it’s always a nail in the coffin that gentrification is in progress—and rents are about to go through the roof."
