True words. In fact, public voting, in a large state context, is fundamentally a means for the government to, not let the people rule, but to offer choices in the government's interests. The choices pre-suppose that there is a general public interest in a given subject and also that there is a common public preference attached to the issue (even if there only ends up being a common public preference after the choice is posited, as it sometimes happens).
By dint of majority vote, the minority receives the message, not only that they go against common, public interest and have thus suffered defeat, but that they were already against the common public preference. The cause and effect swallow one another like a snake eating its own tail.
It is not only oppression of one over another, it is the psychological punishment of dissenters for being wrong from the very beginning. The best that a minority can do in this situation is hope that someday, even if it takes fifty years or more, the general zeitgeist will change its mind in favor of the opposite value (even if that value is only the abdication of another). This is political Manichaeism of the most poignant sort. All issues are dichotomies--the constant play of a good god and an evil god, but which in this case are willing to mis-identify the other and the self, respectively.
Those who reject a specific dichotomy say 'neither the yay or the nay represent my interest concerning the issue,' which is to say that either they're indifferent, or that the perimeters of a choice are too narrow for the scope of their concerns.
It could be better said that voting is as little about the minority vote as it is about the non-voter. It is about providing an apparent providential affirmation of loyalty (better phrased as compliance) thus providing psychological satisfaction for obedience, and a declaration of blasphemy (better phrased as dissention) thus providing guilt for disobedience.
This way, the government gets support for what it would otherwise do even if it was in the unfortunate position of not having any public support.
The villain asking a mother which of her children's life she'd rather spare is the ultimate democrat.
