Maybe I’m being clumsy when I say community – I don’t mean that my friend is only friends with African-Americans, or that he would choose “black” as an adjective to describe himself before any other adjective. What I mean is in line with what you’re saying: my friend considers himself black, as your son considers himself Puerto Rican, for whatever reasons he chooses to consider himself with that identity, so that’s the box he would pick.</p>
