Eh, orwell got his fare share of socialisation with socialism in spain and became a ardent anti-communist (more anti-totalitarian after seeing what this "experiment was all about" when it betrayed the anarchists).
Its like animal farm a staunch criticism of the communist experiment and the societies it would form. The history rewritting was actually a typical socialist society pehnomena, going so far that china basically erased its whole past permanently. Its a incredible young country (barely 70 years old) and had to reimport a ton of its culture from taiwan!
Orwell lived through the hyper akward year, where hitler and stalin where allies and best friends - and thus saw the moscow controlled part of the international defending facists as best friends for a year, right after they stabbed the anarchists in the back in spain.
The Spanish civil war turned him into a socialist. His anti-stalin/anti-Soviet streak was in no way anti-communist. perhaps you shouldn't be so weasel-y with your wording.
