It is no longer liberalism, it is outright Marxism allowing no dissent or opposition.
I think the point of the thread is that it is true fascism rather than marxism, hence the coining of the term “liberal fascism” which I understand as, please correct me, liberal in the sense of the innocuous term they use for themselves, and fascist in its technical sense as governmental controlled, totalitarian monopoly.
Forgive me as I am a language maven above all else. It is not always a good thing as I can become distracted from the point by grammar and terminology. I do NOT correct you except to try to get to the bottom of how you are saying what you mean.
I suspect your thinking to be that marxism must be defined, a posteriori, as suppression of dissent. No?
