no no, i'm saying that leninism (which was later on distorted by stalin) is marked by a rather simple theory (to simplify, i'm not an expert historian either, and i'd welcome anyone willing to correct me =) ): the change in the society is so radical that it cannot occur by itself.
it has to be pushed forth by an elite (they called themselves the "vanguard party"), even against the direct will of the majority (a kind of "we do that for your own good, you'll realize it later"). and communism is not just about economy, but about all the aspect of a state. the "proletariat" is supposed to control the state. in the leninist version, this control was to be _temporarily_ assumed by the vanguard party, (the Bolshevik), which would later on withdraw. anyway, the control over the state is supposedly total, which means all "sectors" of the state, economy, communications, culture, etc.
it is supposed to be one single body with a common thought, each part being useful for the other, etc. so divergent opinions within this body cannot really be tolerated. you can hardly walk if your legs don't want to carry you to the same place

this ended up justifying control of thought etc. the problem, beyond that (if we care to assume for one moment that he WAS right, and that people need to be forced for a greater good, which isn't necessarily wrong by itself), is that repression sort of fed on itself. the more people were controlled and exiled/sent to prison, the more they could come back and complain about that, which led to more and more repression, ending by the crimes of stalin.
it is interesting to note, though, that Lenin was not exactly a "bad guy" (while stalin was a monster, without question). He actually really believed that the single party would withdraw etc. he was much more close to marxism than Stalin. Stalin merely used leninism to take control of the country, but changed many things (the biggest example is maybe the international status of communism. marxism/leninism is about communism as a worldwide regime, while stalin closed the ussr on itself).
as i said, i'm no expert, it just happens that i worked quite a bit on it, so any correction is welcome (and highly interests me =) )
