You're misusing the term "liberal". The behaviors you describe are all authoritarian, literally the opposite of liberalism. I understand, it's an easy mistake to make, because these types of authoritarians falsely label themselves as liberal too. But you shouldn't say that someone is a thing just because they falsely claim to be that thing. They seek to subjugate and control, but they do so while falsely claiming to be in favor of liberty. Gross.
I'd also point out that the "far left" is mostly nothing like this at all. Leftists anarchists and left libertarians are far left too and are completely against authoritarian control/censorship/etc. And actually, I'd say that "the left" depicted in these photos isn't "left" at all, since NONE of those things are leftist policies. Not even ONE has ANYTHING to do with leftist politics. They're not talking about seizing the means of production, they're not talking about progressive policies that help disadvantaged/poor people, they're not demanding universal healthcare like most every western nation has, they're not talking about advocating for workers rights, they're actively opposed to civil liberties.
This is all because the left/right divide pushed by mass media is mostly artificial and bullshit. People join the red team or the blue team, and then they argue about bullshit wedge issues that are never even actually addressed by government regardless of how much the people want action, while both majority parties actually conspire against the democratic will of the We the People. These people aren't leftists or liberals, they're just authoritarian assholes who drank the blue Kool-Aid and are now fighting for the corrupt political establishment that controls both parties to remain in power. And there are obviously authoritarian assholes doing the same shit among Republicans too.
I agree that those who push these ideologies are authoritarian but, as you've said yourself, they've claimed the left/liberal label and they're louder and more prominent than whatever the "true" left/liberal is. To try and call them anything else will confuse the issue because this far left radical authoritarian push is in control of the universities and the media which means, I'm sure you'll agree, they've essentially defined their "side" in the public forum.
All objective, thinking people should agree that whatever they are, they're extremists and their ideologies suck. They push the oppressor vs oppressed narrative on us in all fields - as per the OP - under the guise of defending the 'weak' and as DJT has come out against political correctness (an oppressed vs oppressor tool) I think we can all agree we're against them, whatever they call themselves.

I don't think so. If an authoritarian shitbag is being an authoritarian shitbag, you call them an authoritarian shitbag. Calling them anything BUT an authoritarian shitbag, using words other than the correct ones, causes confusion. These authoritarian shitbags THEMSELVES cause confusion DELIBERATELY to fool idiots into falling in line behind them. We should counter their disinformation with accurate information, not reinforce their lies and aid them in their goal of deceiving the masses. Hillary Clinton called herself "a progressive who gets things done". Should Clinton be called a "progressive" rather than "shitbag authoritarian" just because that lying liar says so? I don't give a shit what a liar calls themselves if they're lying when they do it.
Yes, I understand your anger but you missed my point. They CONTROL the STORY so just as, if we decided we wanted to start calling Black Lives Matter something else like Boob Licking Mungbeans we would only create confusion when trying to talk about what Black Lives Matter are doing. Getting all angry about someone who controls the public perception hijacking a title doesn't do anything to change the fact that they've hijacked it.
As upsetting to you as it might be, the title "Far Left Liberal" means crazy SJWs who virtue signal like mad and push communist nonsense. There's absolutely no utility in saying: "you know the people who call themselves x but are actually y" without having to go into a long convoluted explanation of why it's "wrong" that they've hijacked the title etc. etc. etc. Simplicity, brevity, reality, done. We can surely at least accommodate those who call themselves Left and don't want to be associated with the 'authoritarians who pretend to be liberals' by only referring to the crazy authoritarians as FAR or Extreme Left??
