Honestly, it is pure hatred and plain stupidity.

They don't have the same religion, customs, values, history, etc.

Assimilation takes generations, and the point of integration is that some of their culture is retained. That is how you get pizza snd maffia to New York (to name two random examples), or how languages evolve.

For example, I am from Amsterdam area. The culture there was heavily influenced by Jewish diaspora, and the dialect by Yiddish and Bargoens. The street language nowadays is a mish-mash of English, Jewish, and Arabian culture, as well as that which influenced Dutch language before (mainly English, German, French, Latin, Greek, and I am probably forgetting to mention some). Some parts of our culture are still artifacts from past, we just take them for granted. Last name for example, was introduced by Napoleon. The Austria-Hungarians had influence on the south, and religiously the Catholics are mainly from south (as well as entire Belgium) with the North (above the rivers) being rather Protestants. Language-wise, Belgium's history of three languages is of interest, you could say the same about Switzerland. I wouldn't call USA solely English-speaking either. Heck, just look at the names of places around SV.

Also, would you tip if the food was terrible? I wouldn't. They should be happy I paid (my wife before I knew her once had soup so salty, she send back to kitchen. Chef said was normal. They didn't resolve, yet the soup was on the bill. She and her friends just left).

My recommendation to you? Well, I am not from USA but been in Cali a couple of times. Pivot to people who accept you for who you are. Don't hide where you're coming from, use it to empower you instead.
