Liebknecht's ideal seems to be authoritarian democracy of some form. He's got the hints of the VERY early soviets in him, but seems he can't shake off his noble roots
I concur, thats what i'm getting at from the sparse info we do get on his ideals and past too.
His aim seems to be one of uplifting the people materially and intellectually, the polar opposite of a reactionary conservative. Its not too odd for revolutionaries to come from a class that benefits from the status quo. George Washington was a redcoat and Lenin was descended from nobility. If anything, they make up the central core of the revolutionary intelligensia. Proles make for terrible ideological writers after all.
I don't think he's on left or right on the revolutionary scale perse, the liberal and socialist split has yet to happen to break the coalition that is united against the aristocratic landed gentry. I think he's of the same strain ideologically as the revolutionaries of 1848. Which happens pretty near the story timeframe.

He should be friends with president of Basseland though with how stacked the deck is in his favour lol. (Literally a copy of the anchluss vote lol) Though I do lowkey agree with a period of political tutelage with how backwards basseland is, ala three principles of the people courtesy of sun yat-sen
