I think just about all white people would do well to look around the neighborhood that they grew up in and think about the politics of how it got to be that way. I went to a high school of 1400, and in 4 years there were all of 3 black kids. Turns out this is because no black family was allowed by any bank to get a loan for a mortgage in the area until 1974. White blindness to their privilege is a huge impediment to change - people have literally no idea how different people are treated when there's a different skin color.

The tactic is to get people to actually listen so that they might agree its an actual problem and then actually do something about it.
