How commie should I be? We're supposed to have a book swap and idk if it's NYT bestsellers or Lenin. They've got a lot of "we'll take your name off if you're scared to associate with our group", but looking through the docs and all seems like completely normal stuff.
If you don't know how radical they are, why not bring a book written by a Marxist but that doesn't immediately set off people's alarm bells? Fanon, Gramsci, or any of the French new left writers are acceptable for most radlibs (yet for some reason Marx isn't?)
