...black people universally get discriminated in a systemic fashion in the US based on their appearance. This is not unique to any one state.

Obviously people in different states lead different lives. It's still possible to have a shared identity through facing similar struggles and discrimination.

Just because I grew up in IL and my cousin grew up in CA doesn't mean we can't have a shared identity as Romanian-Americans either.

edit: I have amended this and my parent post to clarify I meant a shared experience, not a unified one.
