Plenty of places in the USA are like that, it's usually just spite or misdirected anger. I had a neighbor like that, fortunately it was never directed at me.
Yup. The United States has a real problem with institutional racism, which is both demonstrable and provable. Racism on a personal level is far more limited, but in my current industry, we have regular trainings to avoid discrimination and disparate treatment (we have volumes of data proving it is still a common occurrence). Policing, in particular, has a serious problem, where certain groups are disproportionately the victims of law enforcement abuse.
The fact that some people have to walk around worrying about how every action they take is perceived and scrutinized by law enforcement and other citizens to the point that common acts of decency (such as plugging in another EV) is the real travesty with American society.
And yes, not recognizing or understanding that discrimination is "privileged" thinking.
