Yes you are entirely correct.
What I was referring to was that Marx or even Lenin would roll over in their graves seeing what Stalin and many of his successors called communism. Their was a distinct political and economic elite that formed that is obviously contrary to communism's traditional ideological focus on the proletariat.
As for my music/ weed analogy I stand by it. For example my dad had to sit under the covers to listen to Radio Liberty ( a western European radio station that acted against communist propaganda). At the time if any heard him listening to it they would have told the police who would have jailed him. Likewise in most parts of the US if you were seen smoking weed you could be arrested and put in jail. If you think the difference is that listening to a radio station isn't harmful and smoking pot is, than you're missing the point of freedom.
People at that time DID feel that listening to anti communist talk was dangerous not only to the individual but to the whole. They felt this way because they were trained to by the state through propaganda. I liken this to how the government has gotten some of us to feel about smoking a plant, not a drug, but a plant. One that grows in the dirt and has been used by humanity for 1000s of years.
You may say that smoking weed isn't for you and that because of that fact you don't care if people go to jail for it's use, but consider, if alcohol was banned there would be people who would say good riddance ( and perhaps rightfully so) but what would you say? You'd say !@#$ that I'm an adult, I'm a human being, I have the right to weigh the pros and cons and make my own life decisions, and if I want to enjoy a drink than the government can't curtail that freedom. You're not a drunk, you're a productive member of society who enjoys a drink, and as long as you're not hurting yourself or those around you, you deserve liberty.
I apologize for making the assumption that you drink but even if you don't drink, smoke, or whatever, if you still feel that liberty comes in degrees you're missing the point.
So in a very real sense, the prohibition of marijuana in the US can be directly linked to the dictatorial censorships of the USSR.
And I'm from Romania, but now I live in Canada.
