That depends on if you believe in Stalin’s ideas of a vanguard or Trotskys ideas of a vanguard. According to Trotsky the vanguard of the workers should be democratically elected.
Every socialist society that has or currently exists practices democratic elections. If you live in a capitalist country, however, you have been taught from childhood that those democratic practices are illegitimate.
Of course, I was taught that Liberal capitalist ran democracy is somehow the only legitimate form of democracy. The question is how should democracy be implemented in a way that ensures the workers have power.
I mean, personally I think the Chinese nailed it. How else do you have government satisfaction rates - as measured by outside observers - that are 90% and above?
Or, hear me out, you can be a non-Marxist socialist, because socialism does not only mean Marxism.
I’m aware, however I assume the person was specifically referring to Stalinism.
