Rewrite my comment to say "my friend experienced no racism". Not more than in his home country at least.

What you said is the same. One is according to what your relative said another is according to what my friend said.

I don't think it's crazy to expect assimilation. We are fascinated with different countries and cultures and we generally consider it's a good idea they exist and are different. Diversity is strength. But they can only be different if they have their own culture and traditions. Would everyone be so fascinated with Japan or Korea if it was not for their culture? Would they be the same without high trust society that is made possible by it?
