Well, there are people that are racist. They are easy to spot because they make no apology about that. There is also systemic, or institutionalized, racism and the current state of law enforcement in the US is a prime example of that. What is interesting is how the systemic racism bleeds into everyone else's minds to form or reinforce their biases. If we can eliminate systemic/institutionalized racism then I would expect that most people's personal biases will eventually disappear.
