Their whole political identity is being against the US. Other than that, a more “adult” response would be to not immediately accuse the US of everything bad that happened. Another problem with the CCP is that they refuse to say the truth when it isn’t convenient to them, they are not transparent at all on their investigations and sources.
In theory yes, and you are going to say all communist countries were not “real communism” now ? The USSR was known for its ruthless and violent political scenes. Leaders condemning their opponents’ families to discredit them for example. North Korea gives all power to the supreme leader (a communist monarchy lmfao). Communist China is the closest to what you might you believe in but it’s insanely violent in the backstage. The closer you are to higher seats of power, the more in danger you are.
On top of that any individual at the top can effectively enact their preferred policies over everyone. Millions died simply because the supreme leader ordered so.
