Leftists always find racial differences impossible to ignore it seems. They dont value people for who they are...they value people based on what color they are.
This condition was exacerbated significantly by the former fractionally-black occupant of the White House who held America hostage to his race-based ideology for eight long years. It takes time to recover from such abuse and constant bullying and race-baiting by a devout Leftist such as he was (and remains to this day).
