Liberals and progressives have very strong faith in their assimilative powers. Elites share the same transnational culture, they are a class unto themselves. There is a parallel between Baathist curation of a diverse elite and the current diversity-represented liberal elite. Immigrants tend to be more socially conservative and religious (examples: Caribbean, South Asia).
Immigrants can also be very patriotic (anecdote of a call centre co-worker who would hum the national anthem to himself every day). In general, immigrants reject “avant-garde” progressivism. Immigrant conservatism makes the democratic coalition untenable. Immigrants show up to the USA and are excepted from black/white racial politics.
The party saying “law and order” sounds good as many immigrants live in poorer and high crime neighbourhoods. Eric Adams, the former cop and mayor of New York, was voted in by black and ethnic votes in Brooklyn. The things that progressives see and assert as obvious are not apparent from a minority/immigrant perspective.
Trump got one third of Muslim votes in 2020. Muslims were triggered by social issues as they have conservative views on sex and family. Trump is a macho guy and some immigrants like a macho leader and want a tough seeming president, the Democrats are “a little limp”. Some successful immigrants have a business-libertarian view and this can also play into machismo.
With American seculars, a huge amount of weight is put into politics. It’s actually good that there isn’t a pure racial divide in politics. Avant-garde liberalism is patronizing, unstructured, diffuse and suffers from purity spirals. Local Republican representatives and officials say “we like you” and apologize for and contextualize Trump.
It isn’t good to teach kids into racial polarization (as avant-garde liberalism does) and imply a racial/moral hierarchy. Avant-garde liberalism is like a religion and its adherents are extremely pious. Which current left-wing figure is funny? The left-wingers used to be the funny ones, Trump filled the vacuum and the left has become even more righteous in response.
