In fact, authoritarian socialism - as practiced in virtually every single Marxist-Leninist country that ever existed - was completely counter to the ideals of Marx and Engels.

Do you mean the Engles who said this:

[T]he 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?

Therefore, either one of two things: either the anti-authoritarians don't know what they're talking about, in which case they are creating nothing but confusion; or they do know, and in that case they are betraying the movement of the proletariat. In either case they serve the reaction

...or is there some other Engles I should know about?

I don't know of any person called Engles who would be significant in this context, so I can't tell you if there is one you should know about. The Engels who said what you quoted above, also said - literally in the sentence preceding your quote:

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.

As always, context matters. And I'll trust the context created by the words and interpretations of respected historians way more than I'll trust some randos on Lemmy who only excel at selective quoting.

Right, and the part you quoted is in the context of what immediately followed. The clarification that he was talking about the eventual ideal, and that in the meantime, using authoritarian measures were necessary to the point that anyone who opposed them was supporting reactionaries.

It should of course be noted that Marx expected a spontaneous, worldwide revolution, starting from the most developed countries. This was something that he got completely wrong, (he was not a prophet) and the socialists who put his ideas into practice had to adapt to the real circumstances that they found themselves in. In the case of a worldwide revolution, of course it would be easier to persue the phasing out of authoritarian measures sooner, since they wouldn't be necessary to protect against foreign threats and subversion (something presumably included in the not-yet-destroyed "social conditions that gave birth to the political state"). Even in such a scenario, Engles was extremely clear that he considered such measures absolutely necessary.

What "respected historians" are you referencing? I haven't seen you cite any. Care to share with the class?
