I keep hearing people say this, and it baffles me. If the majority of people feel a certain way, who's to say it's not the right way? If you start picking this apart it really just comes down to "yeah but the majority can sometimes be wrong", which, I have news for you, applies to the minority as well.
At the end of the day, representative democracy exists instead of "pure" democracy because there's issues scaling the operation of government into something where everybody votes on everything. So we decide to have 1 representative for every N people. To do this, we need to break people into cohorts somehow, such that each cohort is roughly the same size. There's lots and lots of ways to do this, but we seemed to have settled on geographic locations, and sizing so that they (mostly) have similar numbers of people.
But since populations can be extremely concentrated in some areas, cohorting people by geographic location becomes less and less useful. It seems to me in an ideal world, everyone would be randomly assigned to a cohort via some sort of consistent hash, and they would be evenly distributed. Mind explaining to me why this would be inferior to cohorting on geographic location?
