Where superiority/inferiority are missing, inequality must be false, and equality must be true. So yes, when talking about the absence of superiority one is most certainly talking about equality. Painfully simple.
Back on topic.. Marx and Engels.. They seemed to believe fully in race and hierarchy.
"We discovered that in connection with these figures the German national simpletons and money-grubbers of the Frankfurt parliamentary swamp always counted as Germans the Polish Jews as well, although this dirtiest of all races, neither by its jargon nor by its descent, but at most only through its lust for profit, could have any relation of kinship with Frankfurt.""Society is undergoing a silent revolution, which must be submitted to, and which takes no more notice of the human existences it breaks down than an earthquake regards the houses it subverts. The classes and the races, too weak to master the new conditions of life, must give way.""...the Jewish ******, Lassalle... it is now completely clear to me that he, as is proved by his cranial formation and his hair, descends from the Negroes from Egypt, assuming that his mother or grandmother had not interbred with a ******. Now this union of Judaism and Germanism with a basic Negro substance must produce a peculiar product. The obtrusiveness of the fellow is also ******-like.""The most interesting acquaintanceship I have struck up here is that of Colonel Lapinski. He is without doubt the cleverest Pole -- besides being an homme d'action [man of action] -- that I have ever met. His sympathies are all on the German side, though in manners and speech he is also a Frenchman. He cares nothing for the struggle of nationalities and only knows the racial struggle. He hates all Orientals, among whom he numbers Russians Turks, Greeks, Armenians, etc., with equal impartiality.... His aim now is to raise a German legion in London...""Russia is a name usurped by the Muscovites. They are not Slavs; they do not belong to the Indo-Germanic race at all, they are des intrus [intruders], who must be chased back across the Dnieper, etc.""Being in his quality as a ******, a degree nearer to the rest of the animal kingdom than the rest of us, he is undoubtedly the most appropriate representative of that district.
- Letter from Friedrich Engels to Karl Marx's daughter, Laura, speaking about her husband Paul Lafargue, April 1887, who ran for public office in a district holding the Paris Zoo. Engels felt license to write such filth to Laura (Marx) Lafargue, because Karl Marx himself had violently opposed her marriage to "a ******". Marx referenced Lafargue as "the little negro" or "the gorilla". Jenny Marx, the mother, wrote to Engels that she hoped her daughter would not have "ten little ****** boys".There are many other quotes from Engels expressing contempt and arrogant moral superiority towards other groups, such as the Slavs, the natives of India and China ("heredity stupidity"), Irish ("little above the savage...favoring drunkenness... a people related in their whole character to the Latin nations, to the French, and especially to the Italians"), Scandinavians ("rudeness... perpetual drunkenness"), Balkan peoples ("This miserable debris of former nations, Serbs, Bulgarians, Greeks and other thieving rabble, whom the liberal Philistine raves about in the interest of the Russians, deny each other the very air they are breathing, and have to slit each others' greedy throats."), Turks ("This splendid territory has the misfortune to be inhabited by a conglomerate of different races and nationalities, of which it is hard to say which is the least fit for progress and civilization." ) etc.
