The multiculturalism you describe is bad enough, but what's even worse is when foreign aliens who don't have much in common with this country go even further and try to remake the whole country in their own image, such as AOC, Tlaib, the Hispanic migration lobby, etc. They actually believe that not only are they entitled to their own culture in the US (which multiculturalism allows), but that they can impose their culture on the rest of the country. For instance AOC and others like her want to do away with the Electoral College, the 1st and 2nd Amendments, etc. That is unimaginable hubris. They don't want multiculturalism either. They want monoculturalism -- their own!
