Exactly. Antifa is short for "opposed to fascism". Which, you know, is the bad thing where you hurt a lot of people just because they are different from the "group" you defined, with the aim of spoliating the outsiders to enrich the members, or make them an inferior cast, etc...
Having to explain why fascism is to be fought against...
Ugh, what a world. Not even science-fiction writers dared to write such a nonsensical reality.
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.
