The difficulty is that when the electorate is not homogenous, and yet a decision has to be made, a majority must be found one way or the other. That's inevitably going to mean that some voters' views are not taken into account. Even under proportional representation, which comes closer than the majoritarian systems to representing non-majoritarian views, it will be the case that many voters, and perhaps most voters, are not going to be represented in the sense of having their political aspirations implemented, because the majority coalition, whatever that turns out to be, will not include their party. There is no way, no voting system, that ensures that everybody ends up having his or her view incorporated into government decisions.
