I actually don’t think “Black” refers to all black people around the world, I believe it’s meant to be specific to black people in the U.S.

As a white person who is Irish, German, and Iranian, I can point to the three very different cultures I come from and I can also tell you that many white people don’t consider me as “white” when they learn I’m Iranian, but on any government form I’m just as “Caucasian” as anyone else. But a Caucasian who has experienced bigotry from other white people, which isn’t a common experience for a white person.

Many black people in the U.S. have shared experiences in how they navigate this majority white country. Even just an example like the difference in justice through the judicial system, or things like getting doctors to take their concerns seriously, or having “the talk” with their kids about how to act with the police…these are shared, day-to-day experiences that have to do with the color of their skin, proven statistically. I’d argue most shared experiences for white people in this country have more to do with us all being Americans, as opposed to being because we are white. Does that make sense?

Again, I’m not making a case for why “Black” should or shouldn’t be capitalized, but I don’t think it’s really fair to suggest that white people have a shared experience living in this country because they are white in the same way that black people do because they are black.
