If we’re talking about Hungary 56 or the Prague spring then anyone using the word as a pejorative doesn’t know the history and/or what’s going on now. They could just be wildly reactionary I guess.
If we aren’t talking about those specific events then using it as a pejorative outs the speaker as someone with a bad case of brainworms. I guess it’s less lack of education in that case and more being so propagandized you can’t tell up from down but whatever.
