You need to realise that Marx is just a guy. Marx wrote things that can be interpreted as being in support of reformism and things that can be interpreted as being against reformism. He was very racist at times and at others he was woker than 95% of BLM protesters. Marx isn't a god or a hero, nor is he someone who had a dream per-se. He went actively against dreamers and utopians because he saw it as a real danger to make promises that might not conform to reality, while of course opposing naive realism or bargain bin political realism. He was in the truest sense a scientist, a critic, someone who was much closer to a nihilist than a naive activist. He revised his views multiple times throughout his life, as he went from being a romantic to something closer to a systems theorist. To put him into diametrical opposition to Lenin tells me that you understand neither beyond a Wikipedia level reading and that is being charitable.

To say that Lenin personally created the VChK without crediting the chaos and antagonisms is absolute insanity. It's even crazier to say that he was a power hungry monster, as if it were a property that came out of a vacuum. There was a war going on. The stone you sat on while taking a break was a power hungry monster, this isn't even a discussion, nor is it telling us much.

The provisional government failed, and not by some "evil" Leninist influence but because of the PG did not want to drop out of WWI partly because they were banking on being good with capitalist nations, which is a big big big deal. The SR had been in a cul-de-sac and the Bolsheviks yanked the movement out of it. The persecution of the SR needs to be questioned, no freaking doubt. Dismissing the Leninist vanguard however, the success of the Soviet Revolution, is deeply disrespectful to the proletarians who were at the base of the movement.

I have to repeat that I am not even a Leninist. I really do not believe that he should be worshipped and there were certainly questions of organisation that could have been handled differently. You are misrepresenting things egregiously.
