Systemic racism works mostly on implicit bias. So people can't easily tell whether they're doing it or not. Which means conscientious individuals trying to fix our own behaviour - while it can and does reduce bigotry - cannot fix the systemic stuff.
Once, I firmly believed that the world was merely an accumulation of millions of individual actions. But what about network effects, and other ways the social background radiation can change and warp individual choices, without our awareness?
