Nomenclature alone is meaningless. Is the Democratic People's Republic of Korea which professes anti-fascist messaging and motives both democratic and anti-fascist? I wouldn't assume every "antifa" group is principled and accurate in its diagnosis of what fascism is and who are acceptable targets for their outgroup directed aggression.
NK is a dictatorship. I don't know where you got the misunderstanding that they would be "anti-fascist".........
Anti fascist => anti dictatorship.
Anti fascist means that you don't like fascism and that you are not going to let it happen passively.
(Tired of explaining the obvious. But I guess that somebody has to.)
A dictatorship mechanically leads to a situation where the governing group is working for their own wealth, thus in this case the "group" is the governing class. The extent and definition of that class is voluntarily limited so that wealth and power converges to them.
Now you see it? Yes that is a fascism, meaning that:
dictatorship => fascism
And the reverse stems from the "groupism" (i.e. tribalism) of fascism, which entails that you need exclude large portions of the population from the political system.
As this "group" definition becomes narrower and narrower (in order to make more wealth converge to the alleged "true humans" of its center), it becomes a harsher and harsher dictatorship, and finally a strongman regime.
fascism => dictatorship
Perhaps not, but this administration is in no way principled or accurate in its diagnosis of anything so their labelling of any group doesn't deserve the benefit of the doubt.
