Because it is about race.
Please read the article I linked in another reply to you.
My neighborhood was prosperous when it was systematically stolen from the black people who built it. They literally razed a thriving business district. And then the land sat empty for decades, only in the end to be sold to property developers.
They used eminent domain to steal people's homes and businesses in a way that was blatantly criminal, but the victims had no recourse given the courts and entire rest of the political structure was complicit in the actions.
And variations of this story played out everywhere across America.
So yes, the fact that a neighborhood is historically black is relevant, because it shows the events of today are part of a continued arc of injustice.
