I am completely unfamiliar with anything like that happening in 1984. I am familiar with Orwell writing about the decline of logical reasoning in favor of vague and politically charged platitudes--like calling a political administration "Orwellian" when you're supposed to be discussing a legal decision.
Being marked an enemy of the state for disagreeing with the state to me sounds like thoughtcrime, plain and simple. How much more Orwellian can you get?
