Roughly half of voters voted for this. Non-voters do not count in a democratic system. I'm not counting "people", I'm counting voters. Non-voters are quite simply irrelevant. If you don't make your voice heard, then you're implicitly allowing others to speak for you.

> Roughly half of voters voted for this.

Substantially less than half the voters voted for it, while more than half voted for one specific alternative.

They certainly count as part of the country. And, to the extent that they are nonvoters because they are systematically excluded rather than than voluntarily abstaining, the system isn't democratic to start with.

But, that aside, in any case, in a democratic system, an option with minority support in the electorate doesn't get selected over one supported by the majority, so I'm not sure why you are raising what happens in a democratic system to defend your argument, since it instead defeats it.
