Look, I get your disdain for Antifa, and I'm not a fan myself. But that logic is pure crap and is like saying that's all Trump's problem is when he won't condemn literal fucking wannabe Nazis and white supremacists. It also completely dismisses any and all nuance while simultaneously lessening how horribly fucked up the false equivalence that Trump and many like him have been spouting for years. The people calling Black Lives Matter as terrorists are the exact same type of people that condemned the Black Panthers (who absolutely were wrongly called terrorists when they were in fact arming themselves in defense of the outright murder and terror that law enforcement was doing against people of color at the time). That's why the professor is making the point, as just labeling Antifa like that, effectively promotes law enforcement to do horrible shit that is not justified. Not only that but it completely ignores the outright hypocrisy and how the false equivalency does disservice in both directions (makes one group look worse, while also tries to justify the actions of other groups that are doing worse shit and being defended by the same people making the stupid claims). In this case it is the people that support right wing "militias" that have proven to be far far worse and commit outright terrorism and a whole host of other awful things, often in the name of white supremacy or various fucked up insane beliefs that fall in line with that general mentality.
I'm sorry, you go be with the authoritarians, I'm a liberal.
There are two sides here, liberals vs fascists/authoritarians, you side with the fascist/authoritarians and that is on you. Anarcho-communists are not fighting to end some kind of injustice, they want to make the injustice their style rather than the opposing sides style and if you stand up for liberalism and democracy you'll oppose both sides.
Yes, one side is worse than the other in one place, the other firebombs the police in another to end the idea of liberal ideas.
It's not a disdain, I don't think you know what the fuck you are doing across the pond. We have been dealing with these fucktards for a long arse time and they are not any better than the EDL or the football lads, in fact, on the whole they are worse.
Their goal is to end all political parties, they don't give a fuck about you or democratic rule, rule of law or anything like that, they are literally opposed to every such sentiment.
One does not need to praise Stalin to loathe Hitler and his likes.
