Marxist sympathizers are no heroes.
Saw the movie. Liked it but was actually too lenient on Oppenheimer. He had multiple affairs—not just one—during the 40s and 50s.
If he had been anyone else, he would have lost his clearance a long time before he actually did.
I actually admire him as a scientist. But you just couldn’t screw randos and hang out with Communists and expect the government not to notice in the 50s.
