Yeah I mean Kitty. To my knowledge, it seems like what did they did include of Kitty (and also Jean) was pretty much accurate, just missing a lot of background details. Kitty was an actual member of the Communist Party but she did eventually leave it, which would be why she wasn’t in it at the time of the Manhattan Project and the Oppenheimer hearing. Though, you’ll notice when she gets interrogated at the hearing she refuses to give up anything about the Party and turns all of the prosecutor’s rhetoric back against him. It reminded me of Paul Robeson’s famous testimony to the HUAC. Speaking to her earlier dedication to communism, she had actually tried to go fight in the Spanish Civil War with her previous husband but medical issues kept her from being able to make it. It seems as though his death in the war and the many failures of western communist parties disillusioned her from the cause, and I would assume the rising red scare culture didn’t help.

Einstein yes, but he wasn’t actually a member of a socialist party, he just supported it personally and wrote arguments defending it.

Oppenheimer, I think not entirely though he was surely sympathetic at least. His wife, his brother, and his best friend were card-carrying communists, but idk of any evidence that he ever espoused socialism/communism himself, outside of hanging out with communists a lot. He was very much accused of being a communist after the war ended, but pretty much every famous person who wasn’t a fascist was targeted by mccarthyist witchhunts and accused of being communist

I once encountered an old friend of mine at Black Lives Matter rally. He apparently joined a white supremacists org and was counter-protesting with them. Wished I could have confronted him, but the police had the two sides separated by fences. Him and his buddies ended up getting arrested after they picked a fight with someone
