Stop using this weaselly euphemism. What you really mean is black people, but you know it's wrong to group people by the colour of their skin rather than the content of their character. You're still a tribal moron though, so you can't quite manage to put that wisdom into practice. Instead, you replace it with the softer, more socially-acceptable euphemism of "community". Black activists do it to make it appear as though they speak for all black people. White liberals do it because it makes them feel good, like they're making a positive change for the world (narrator: they're not). Both groups are distilling people down to an immutable characteristic and pretending they all share the same thoughts and values. We collectively agreed that this was wrong when white supremacists did it, and the reciprocal form is just as wrong, albeit morally and socially fashionable in current_year. If you consider yourself a liberal, treat people like individuals. Same goes for all other "communities". There is no black community; there is no gay community; there is only your local community.
