We do want majority decision making, but Democracy, outside a theoretically extreme sense, is self-determination for all, not just the majority.

That's the reason for rule of law, human rights, and limited government - to protect those without power. The people with power always have had self-determination.

Totally agreed; nevertheless, any voting system capable of expressing the desires of voters should result in an outcome that better meet their desires than the desires of non-voters. If it didn’t, why would anyone vote?
