On your question about dissent and opposition: I'll refer to Lenin because he sums it up rather well, and his words ring true today.
"7. “Freedom of assembly” can be taken as a sample of the requisites of “pure democracy”. Every class conscience worker who has not broken with his class will readily appreciate the absurdity of promising freedom of assembly to the exploiters at a time and in a situation when the exploiters are resisting the overthrow of their rule and are fighting to retain their privileges. When the bourgeoisie were revolutionary, they did not, neither in England in 1649 nor in France in 1793, grant “freedom of assembly” to the monarchists and nobles, who summoned foreign troops and “assembled” to organize attempts at restoration. If the present day bourgeoisie, who have long since become reactionary, demand from proletariat advance guarantees of “freedom of assembly” for the exploiters, whatever the resistance offered by the capitalists to being expropriated, the workers will only laugh at their hypocrisy.
The workers know perfectly well, too, that even in the most democratic bourgeois republic “freedom of assembly” is a hollow phrase, for the rich have the best public and private buildings at their disposal, and enough leisure to assemble at meetings, which are protected by the bourgeois machine of power. The rural and urban workers and small peasants—the overwhelming majority of the population—are denied all these things. As long as that state of affairs prevails, “equality", i.e., “pure democracy", is a fraud. The first thing to do to win genuine equality and enable the working people to enjoy democracy in practice is to deprive the exploiters of all the public and sumptuous private buildings, to give to the working people leisure and to see to it that their freedom of assembly is protected by armed workers, not by heirs of the nobility or capitalist officers in command of downtrodden soldiers.
Only when that change is affected can we speak of freedom of assembly and of equality without mocking at the workers, at working people in general, at the poor. And this change can be affected only by the vanguard of the working people, the proletariat, which overthrows the exploiters, the bourgeoisie.
8. “Freedom of the press” is another of the principal slogans of “pure democracy”. And here, too, the workers know — and Socialists everywhere have explained millions of times —that this freedom is a deception because the best printing presses and the biggest stocks of paper are appropriated by the capitalists, and while capitalist rule over the press remains—a rule that is manifested throughout the whole world all the more strikingly, sharply and cynically—the more democracy and the republican system are developed, as in America for example. The first thing to do to win really equality and genuine democracy for the working people, for the workers and peasants, is to deprive capital of the possibility of hiring writers, buying publishing houses and bribing newspapers. And to do that the capitalists and exploiters have to be overthrown and their resistance oppressed. The capitalists have always use the term “freedom” to mean freedom for the rich to get richer and for the workers to starve to death. And capitalist usage, freedom of the press means freedom of the rich to bribe the press, freedom to use their wealth to shape and fabricate so-called public opinion. In this respect, too, the defenders of “pure democracy” prove to be defenders of an utterly foul and venal system that gives the rich control over the mass media. They prove to be deceivers of the people, who, with the aid of plausible, fine-sounding, but thoroughly false phrases, divert them from the concrete historical task of liberating the press from capitalist enslavement. Genuine freedom and equality will be embodied in the system which the Communists are building, and in which there will be no opportunity for massing wealth at the expense of others, no objective opportunities for putting the press under the direct or indirect power of money, and no impediments in the way of any workingman (or groups of workingman, in any numbers) for enjoying and practicing equal rights in the use of public printing presses and public stocks of paper.
9. The history of the nineteenth and twentieth centuries demonstrated, even before the war, what this celebrated “pure democracy” really is under capitalism. Marxists have always maintained that the more developed, the “purer" democracy is, the more naked, acute and merciless the class struggle becomes, and the “purer” the capitalist oppression and bourgeois dictatorship. The Dreyfus case in republican France, the massacre of strikers by hired bands armed by the capitalists in the free and democratic American republic —these and thousands of similar facts illustrate the truth which the bourgeoisie are mainly seeking to conceal, namely, that actually terror and bourgeois dictatorship prevail in the most democratic of republics and are openly displayed every time the exploiters think the power of capital is being shaken."
"Throughout the civilized world we see Bolsheviks being exiled, persecuted and thrown into prison. This is the case, for example, in Switzerland, one of the freest bourgeois republics, and in America, where there has been anti-Bolshevik pogroms, etc. . From the standpoint of “democracy in general", or “pure democracy", it is really ridiculous that advanced, civilized, and democratic countries, which are armed to the teeth, should fear the presence of a few score men from backward, famine stricken and ruined Russia, which the bourgeois papers, in tens of millions of copies, described as savage, criminal, etc.. Clearly, the social situation that could produce this crying contradiction is in fact a dictatorship of the bourgeoisie."
In every country where freedom of assembly, press, etc, have been maintained and which tries to implement socialism - I think of Venezuela today, Chile in 1973, and Indonesia in 1965 - the capitalists organize for the violent overthrow of the government. More than a million Indonesians paid with their lives for the fact that "freedom of assembly" and "freedom of the press" were allowed under Sukarno. The Suharto dictatorship which followed slaughtered all the Communists.
So like Lenin said, the choice is not between liberal democracy & dictatorship - the choice is between dictatorship of the proletariat & dictatorship of the bourgeoisie.
