How do you know they complain about the weather, if they don't speak your language?

That is maybe the biggest fear mongering dogwhistle you've dropped so far.

That's a rhetorical example of a human, every day conversation someone might have.

The fact that you took it literally and express concern about its veracity is very revealing. I don't generally police what my neighbors talk about.

No, it's a reasonable question. Language is how 90% of communication happens. 如果我用中文說話，你根本聽不懂我在說什麼。只有聽得懂鄰居和社區裡的人在說什麼，我才會感到自在；如果聽不懂，我就不會有這種自在感。I've a significant chunk of my life in places where people don't speak my language and it's not a comfortable situation to be. Sure I have some anxieties but everyone does and if you say their feelings are invalid then I'm not sure which of us is more intolerant.
