Because what I want in the world and what is reality are two different things.
Until society changes and is ready to accept that black people are ok in, and maybe even expected, white areas then you have to consider the societal expectation of no black people in the white area, even if that may not be ideal or even right in the realm of black considerations.
Perhaps unfortunately, but most whites aren't going to just flip a switch in their brain and go "I'm okay with seeing black people in a white-only area". Especially if they've ever been traumatized by a black person.
As I said, unless it is made explicitly clear to expect to maybe see black people in an area where, in basically all of modern history, it had been no-blqck people the entire time before, then I'm going to err on the side of caution and say that the societal expectation takes precedence
See how fucked what you're saying sounds?
We don't cater to the irrationally hateful, our duty is to aid those that are being persecutes like this trans woman was.
