Way back in the 1980s, when I was in college, we had a tent city on the UC Berkeley campus to protest the Apartheid regime in South Africa. Lots of parallels to what's been happening on campuses recently with the Palestinian solidarity protests, including violent police crack downs.
During this time, author Kurt Vonnegut came to speak in support of the movement, and against Apartheid.
I recently found this amusing clip
of Vonnegut explaining the different types of character arcs a story can have.
