Why isn't this a thing? An advanced communist ideology with the benefits of the respect of human rights, especially freedom of speech? Also communism as a reform movement, not a violent revolution.
I should start my own party and write a manifesto, but that sounds like a lot of work.
I think after the Stalinist disaster, Communism needs a new branch to distinguish itself, both from the soviet horror and the rest of the original post-Lenin mess. A new manifesto would have to include the coming revolution in automation, which Marx of course didn't predict.
