Does Oppenheimer downplay the dangers of Communism ? Full Review

Hello my fellow content seekers, I finally went back to cinemas. Oppenheimer is the first film in over a year that I have been interested enough in to go and see in theatres, and it did not disappoint.
But I've heard people suggesting it might be downplaying the dangers of communism, painting that era as a sort of paranoid witch-hunt where people saw communists hiding in every shadow, and used that paranoia to justify the persecution of many 'innocent' people. I can see how you might view it that way, but I disagree.
