It's worse when you say you're a Communist or say Communism is good, and people agree, but when you advocate for AES or advocate for standard Marxist theory the same people flip on you and call you brainwashed.
I haven’t gotten that far with people yet. I have only met people who say “no communism” but “socialism” or “Democratic socialism” or “social democracy”
There are two kinds of deviations on the left, right-deviations (aka opportunists) that are succdems and such, basically defending capitalism and always siding with libs against communists, and the left-deviations (also called ultras, leftcoms etc. often including anarchism) who refuse to acknowledge every real-world attempt at socialism as "not real communism", "statism", "authoritarianism", "state capitalism" etc. because real world has a habit of clashing with their ideals. Some short reading.
If you want to met those latter people, probably just wait for the answers for my comment here, since there's many of them here on fediverse.
I find it's valuable to push people on the whole concept of democracy and getting them to understand that politics is about organization of the economy first and foremost. The key question is why we work in the first place and who decides on what the purpose of work is. If people believe in democracy then it necessarily has to extend to organization of labor as well. Having a democracy where a handful of oligarchs decide why and how people work is a farce.
