I Can Fix It!

Again, moving from comments to post.

The handiest guide I've seen for white people to help fix racism at fixracism.com, compiled by Damali Ayo.

1. Admit It.
   
2. Listen.
   
3. Educate Yourself.
   
4. Broaden Your Experience.
   
5. Take Action.

It is available as PDF file, which also includes a guide for people of color.
