Not really, no. To a capitalist, all forms of leftism is 'authoritarian,' because they consider private property natural and oppose leftists 'stealing' in.

'Authoritarianism' just isn't a particularly useful term because nobody who uses is is ever actually categorically opposed to forcefully compelling people to do or not do things. They will always have a build in exception for what ever they consider to be 'legitimate authority', and what they consider justified authority will just depend on what political philosophy they ascribe to. So really calling the word just means "someone with a different political theory to me with regards to legitimate authority."

Why do the anti-authoritarians not confine themselves to crying out against political authority, the state? All Socialists are agreed that the political state, and with it political authority, will disappear as a result of the coming social revolution, that is, that public functions will lose their political character and will be transformed into the simple administrative functions of watching over the true interests of society. But the anti-authoritarians demand that the political state be abolished at one stroke, even before the social conditions that gave birth to it have been destroyed. They demand that the first act of the social revolution shall be the abolition of authority. Have these gentlemen ever seen a revolution? A revolution is certainly the most authoritarian thing there is; it is the act whereby one part of the population imposes its will upon the other part by means of rifles, bayonets and cannon — authoritarian means, if such there be at all; and if the victorious party does not want to have fought in vain, it must maintain this rule by means of the terror which its arms inspire in the reactionists. Would the Paris Commune have lasted a single day if it had not made use of this authority of the armed people against the bourgeois? Should we not, on the contrary, reproach it for not having used it freely enough?

The liberals are still doing this in 2025. We shouldn't really be surprised I spose.

Anarchists tend to be smart enough to not use the word tankie.

There are exceptions of course.

Generally not. Anarchists and Marxists want separate goals and have separate means, but Liberalism is a separate ideology.

No, but a lot of liberals consider themselves anarchists.

It will happen in a few years from now.

Tankie = derogatory term for Marxist. It's that easy

Communism and fascism are entirely different, and conflating the two has roots in Double Genocide Theory, a form of Holocaust trivialization and Nazi Apologia. The Nazis industrialized murder and attempted to colonize the world, the Soviets uplifted the Proletariat and supported national liberation movements such as in Cuba, China, Algeria, and Palestine. I recommend reading Blackshirts and Reds.

Authoritarian communist, essentially

Wikipedia has a good article about the term
