Soviet Russia was not an egalitarian society, it was a brutal dictatorship governed by an effective ruling class of party members. Mainland China is the same. If that’s your standard of “leftism”, you’re drawing the line somewhere to the far left of any self-proclaimed communist party that has ever held power in any country. This is clearly absurd.
You’re the commie version of those annoying right wingers who like to start semantic arguments that the Nazis weren’t really right wing.
Leftism is an incoherent and false ideology fundamentally unsuited to the governance of human societies. Once you recognize that fact, the hypocrisy of actual leftists will cease to surprise you.
