Earlier quoted context omitted.
“Communism” != “Soviet style totalitarianism”. There’s nothing inherently wrong with being a communist. You don’t have to agree with it as a political philosophy (I don’t), but it’s no worse than being a capitalist.
Let's not go down the "those aren't real communists" route. The communists in the West were by and large always very cozy with the SU. Hell, they loved Stalin so much and wanted to hear so little that Orwell sat down to write a fable to explain the issues to them.
There is a difference between communism and nazism.
Communism is simply the belief that the workers should own the means of production. It's like being a "witch". You might think it's complete nonsense and doesn't work in the real world (I'd agree with you), but if people want to be witches (or wiccans or whatever), they should be allowed to be.
Nazism, on the other hand, is an inherently evil ideology. Hopefully, I don't have to explain why.
And once again, you've mistakenly conflated communism with totalitarianism (which is what 1984 is actually about).
