I've read the State and Revolution, I'm well aware of what the dictatorship of the proletariat is. Lenin endorses the use of state violence to coerce members of the proletariat who don't support his cause. I guess i can go dig out my copy and find a supporting quote or two if you really need it. I had a couple of Marxist professors who made sure we covered that and Das Kapital pretty extensively. It's been a minute, but I remember it standing out because of the sheer contrast between Lenin's perspective and Engels'.
