All this talk of xenophobia and racism, which I get are indeed often reasons why people do this, but there’s a certain show of lack of respect for the new home country if there’s not even an effort made. If someone is visiting a country, I get there’s an exception, but if someone moves to a country, it shouldn’t be uncalled for to expect at least a minor effort to learn just enough of the new language to transact/survive. That’s something I see a lot as an American, and it frustrates me- Folks who move here and have been here for years, but can’t learn enough to at least sort of transact. I have so much respect (often more for them than natives) for those who learn even a couple words so I can do my job to help them, but then there are folks who I’ve seen for years that still refuse to learn a single word of English, so we play the mime game trying to figure out what they want. If I move to another country, you bet your ass I’m not going to expect them to speak English, and I’ll do what I can to at least learn some words or phrases so I can interact with the populace around me. I feel like that is one of the most significant forms of respect for a new home country that one can show. Not everyone is as nuanced in their outlook and opinions, and a lot of those folks are indeed racist xenophobic.
