What made you upset about the Lumpenproletariat? Either way, Marx describes a bit about what a Socialist state might look like in Critique of the Gotha Programme, but is careful not to actually decide anything or give a template.
I understand that you are saying the Bolsheviks were reactionaries. The Bolsheviks claimed the Anarchists were counter-revolutionaries. What evidence do you have that the Bolsheviks were against implementing Socialism and eventually Communism?
Reactionary is specifically used for enemies of the revolution, not the ones carrying it out.
I am not defending the killing of the Anarchists, but questioning the language of “reactionary” as used by you.
