It's interesting you mention "multiculturalism". IMO, the opposite of that ("monoculturalism"?) could be equated to tribalism. Which you rant about frequently.
So, tribalism is bad, but multiculturalism is also bad? There aren't really any other alternatives that I can see. You gotta pick one.
Other nations have more problems with multiculturalism because they are NOT nations of immigrants**. In the USA, we have absorbed people from all over the world. The white supremacists like pretend it isn't so, but it is. Even they came from Europe.
**Anecdote: in grad school, our coalition included a few Irish universities. So we had students travel to Arizona to work on our project (gamma ray detection). One such student had never seen a black person in person. She was in her twenties, and had never seen an actual black person. I have encountered black people my entire life, from at least elementary school.
