I've since tried. As another poster said it doesn't read particularly well and I got bored, so I just tried to find a funny quote to relay. But it's pretty dry and conventional. There was a chapter on how American Communists mistreated homosexuals though, which was of course written from the perspective of someone who hates homosexuality anyway.
Marx was famously an atheist. He wore a fedora. He attended the Satanic Temple. He had a Baphomet tattoo on his left thigh. He talked about psychedelics a lot more than he took them, but he did take them. You know, atheist stuff.
