Racism is real. Racism affects and infects all of us.
This is not a bad thing to admit.
Things have been this way for millions of years, helping us survive. The biological and sociological systems that make racism and other forms of prejudice tick are not something we can overcome without long-term intentional work on ourselves and our systems. By admitting the existence of racism in ourselves and our cultures and nations, we can address racism and make a better world.

TL;DR:
This doesn't mean that prejudicial behavior is inevitable, Schaller says. “These prejudices tap into very ancient parts of our minds, and it's happening at a very quick, automatic level,” he says. “But we have recently evolved parts of our brains that allow us to engage in slower, more rational thought. When I experience that fear in a dark alley, it may take me another half-second for a more rational thought to kick in, but I'll get there, if I have the motivation and means to do so.”
