Just look at literally every Western "diverse" country or city.
Difference is that all humans are "biologically compatible." It's what makes you human. Cultural incompatibility is a good argument, but throwing out terms like biologically incompatible will get an eye raise.To put it bluntly, humans from different areas of the globe have different genetics. This can affect their behaviors.
Their behaviors can affect their culture.
Their culture can affect others.
And enough people having a shitty culture fucks up all our lives.
Tl;dr
Look at Chicago and Detroit and ask yourself why Japan doesn't have their issues. Maybe just maybe the Japanese are culturally and biologically superior if you want a safe and productive society.
Humans MAY in the future diverge where that is a thing, but right now you can raise a human from one culture to be part of another culture.
