The insidiousness of racism is what really impacted me. I knew it was like an illness that affected a person's whole worldview but I didn't appreciate how systemic and foundational it is. I felt naive about how the cards are stacked to favor white people of power in nearly all circumstances and that of course, racist people make racist policies so why is it surprising that our country has a racist history. I used to be afraid of our country's racist history because of what is says about my white ancestors. But, I don't feel afraid any more.
