Do you understand the difference between proportional representation voting vs. non-PR voting?

"Democracy is a form of government in which all eligible citizens have an equal say in the decisions that affect their lives. " - Wikipedia

A republic isn't by default a democracy. Non-PR voting doesn't allow all citizens to have an equal say because their vote doesn't count if they vote for smaller political parties; At minimum it's not taking away seats from other parties, and not showing the genuine support for smaller parties -- and the bigger political parties know this and is why they want to keep the system this way.

I figured s/he was making a more nuanced point, e.g. the influence of money in politics, not the one you are implying. Id you are right, I recind my upvote!
