There are so few instances of outright rank racism directed at blacks by whites that the race-hustlers have to make up scenarios and stories that "might" be racism to keep the racism narrative going. I would bet many wives of ex-presidents could walk around many places without being recognized.
Heck, half the country doesn't know who Joe Biden is and would probably not recognize him if he were out and about without his SS detail.
This is just lib race-mongers trying to keep the Evil Whitey narrative going. Whites are racists for noticing black people walking into a room, and they're racists for not noticing a black person walking into the room. The needle is right on the total insanity indicator.
