Blacks can either hate it for two reasons: Pride or secret acknowledgement that they need Whites

Either they support it because they buy the bullshit that the Civil Rights movement was a grassroots protests led by blacks and ended segregation. They may have desire to "stop gentrification" and shit like that for their neighborhoods but ultimately never go too far with it due to their blind support of the Civil Rights

Or they secretly realize they need Whites to maintain the level of civilization they are comfortable with
