/lit/ - Literature

I have a lot of discussions with my gf (who is black) about race, for the last couple years but especially now with all this happening.
I've never cared about political activism but she thinks that waving signs and getting in people's faces is going to change the world.
Whats good /lit/ on activism and protest culture that I can read and learn so when I spill my anti-protest drivel I can at least say I've read such and such?
