That’s the problem, though, with these arguments about electoral reform. It comes down to discussions about which party it does or does not benefit and why it might be a good thing if the result doesn’t reflect the voting.
If the reality of people’s votes is not reflected in the result, then that’s not democracy and there should be no pretense that people either want or actually live in a democracy because it’s a deliberately and blatantly skewed system. Not only is it demonstrably unfair, it feeds into the feelings of resentment and mistrust that are already at dangerous levels. Those feelings, themselves, already skew people’s voting.
