nope, the Marx Leninist idea of a vanguard party doesn’t even purport to be communism, rather the idea that you must go through a phase of state capitalism to grow the nation’s capital after a revolution (revolutions tend to destroy capital) before you can enact communism, it’s just that during the age of ML Fascism was the popular new political ideology, and Lenin did heavily base the idea of the vanguard party on a lot of the same basic understanding as the fascists did.
and of course the fascists did what they do and killed the lefties
