Well, look at Leninist-Stalinist Russia and define how exactly that wasn't 'State Capitalist.' Leninists protect their right to wield the club by following their doctrine which basically states 'radical intellectuals' have the right to hold State power and force harsh rulings on it's people. "Red Bureaucracy" or how Bakunin says the "new class." They basically become 'State Priests' as in the Bonapartist State which Marx denounced himself.
