A communist government is intended to be a dictatorship. In that sense, no different from a fascist government. Dictatorship of the proletariat is a myth of course simply because of human nature. It never happens. It cannot be otherwise. And someone will run the show - invariably an alpha male like Stalin, Mao, Mugabe, Castro, the list is long. http://www.conservapedia.com/List_of_dictators.
> A communist government is intended to be a dictatorship.
Not necessarily at all, and not only in theory but also in practice. The Kibbutzim[1] in Israel are a relatively successful form of communism -- granted, not on a state scale -- and lasted for about 100 years now (though they can hardly be called communist any more), and they have always been democratic (even if in practice they were sometimes oligarchic, but not much different in that respect from many democracies). The Kibbutzim were a particularly radical form of communism, where children were raised collectively, and lived away from their parents (this practice was particularly criticized in Israel and later stopped in most Kibbutzim).

There are really so many senses in which communism differs from fascism so completely (e.g. one is founded on exploitation and the other is founded on anti-exploitation) so that even if they were similar in one sense, comparing the two is not very useful. The only sense in which the two can be said to be similar (and this one applies to many ideals, even to opposing ones) is that they're both utopian.
