"Definition of democracy
1a : government by the people especially : rule of the majority"
Having 51% of voters electing MP's that hold 100% of the power is more democratic than 39% of the voters electing MP's that hold 100% of the power as we have in our current system.
Yes, I would agree with that. But democracy isn't perfect and so it becomes a question on how we do the best to apply the principles.
And fwiw, democracy has proven to not work any better than other systems in a modern world where doing the right thing for the masses is of the most importance. But that's getting a bit ahead of the discussion here.
I'd rather a bit more gridlock if the majority have a say than unfettered power of the minority.
Your preference would need to be put to some test and that's the reason why I've asked you to invent some scenario in which the test could be imagined.
Keep in mind how democracy has failed in the US too!
I tend to prefer minority governments in Canada because there's more consensus and other parties to put a check on the ruling party's power, despite causing more gridlock. Right now the minority Liberals tend to team up with the NDP to get bills passed, which means the MP's of ~49% of voters are represented in these two law-making parties, instead of only 39.5% of voters represented in the previous Liberal majority government.
I like it too right now with the NDP or some other party's MP's being needed by the Liberals, but then that's suitable to my personal politics while it's not suitable to others. And yet I still have to question the political priorities of the NDP at times. It 'does' though accomplish some of the goals of PR without having to go all the way there.
If a situation should develop within a PR system in which one party's priorities are close to the opposite of the other major party that is supported by a large per centage of the people, the gridlock could be created in a way that it's not created with the NDP supporting the Liberals.
And so once again I suggest that we try to create a scenario in which the PR system could be imagined to be tested. I'll suggest healthcare for lack of something more suitable as a bone of contention. Can you take that further by introducing something specific on which the two major parties would cooperate to make PR work.
I'm not particulary stuck with that topic, but you've failed to recommend anything else, even though I said I would be agreeable to discuss your personal issue of taxation.
