Yup, but the people making both external and internal propaganda must have been influenced by some memes, whether USSR-mainstream, radical, doublethink-heavy or even disapproved ones. I want someone who's denouncing Soviet/communist influence to look at what the people at the source of that influence thought, in detail.
I have found this most wonderful (if fairly lengthy) article, and thought you would enjoy having it brought to your attention.
It is so good, I think we should include it among the references in the "Politics is the Mind Killer" wiki page. But, before that, I submit it to you, and ask you: is there anything in this article that would warrant its exclusion from this site? I mean, besides the fact that it is about politics, and written by a notorious Social-democrat (And is that in itself grounds for exclusion?).
