There is a big difference between racism - actual animus toward another race - and unconscious bias, or assumptions we make about people based on the way they look, often without realizing it.
We do society a big disservice by conflating the two.
If a cop chokes a black man for selling cigarettes, is he a racist? Maybe, maybe not. But he certainly harbors unconscious - or conscious - bias.
The President’s long history with race suggests he harbors both, by the way.
