It's certainly reasonable to argue about whether this actually applies; but I don't think that it represents a useless dilution of the word to think that it might. (Well, not 'dictatorial', but the rest of it.)

literally that it is reasonable to argue, i.e., that neither position is obviously irrefutably true; and also I think I've created enough of a de-rail already here; but, if I had to make an argument for authoritarianism, I think that I would claim that the concept of free-speech zones instantly implies, for some parts of US government at some times, more respect for authority than personal liberty.
