The worker's councils were recreating the basis of capitalism and interfering with regional and national interests in favour of their own petit-bourgeois aspirations. They wanted to become a labour aristocracy and they threatened the economic foundations of proletarian democracy with their narrow, self-interested trade union consciousness. Yugoslavia's model is a perfect example of what would have happened if this was allowed to proliferate and to threaten the revolution.

If the Mensheviks didn't want to get outlawed then maybe they shouldn't have aligned themselves with the interests of the aristocracy and the Kadets over the proletariat 🤷‍♂️

Imagine being salty that the October Revolution overthrew the bourgeois Provisional Government. The soviets had established themselves as the legitimate organ of proletarian power and they seized political power because the Mensheviks and the Constitutional Democrats did not represent them.
