Democracy's success isn't measured by how one person feels about an incoming government - it's based on the strength of democratic institutions, and liberal democracies are further characterized by strong civil societies and human rights regimes. If the majority of Canadians want a Conservative government in power - why do you feel that preference shouldn't be accepted?
It doesn't sound like you even want a democracy, you just want a one-party autocracy, given that you feel that people shouldn't be allowed to have fluid political preferences. That's a failure of democracy - a one party state with all decisions made by someone on Lemmy.
I'm not happy about an incoming Conservative majority government either, but my gut reaction isn't to start claiming that democracy in Canada has failed. I'm able to calmly acknowledge that there's a party right now that is probably going to win a plurality of votes and ridings because the majority of voters align with their messaging. That's not a failure of democracy, that's a success of democracy.
All governments everywhere frame their decisions in a way that is akin to gaslighting. If the majority of Canadians disapprove of Pierre's actions, or we lose the trade war with the US in a meaningful way that deteriorates our standard of living, then they will lose the next election. It's that simple.
People blame Trudeau now for all of their ills, as though that he has the power to magically make the economy go up and down with a snap of his fingers. The Liberals made investments in key sectors all the time, including housing starts, climate change and social justice, many of which are never going to be meaningfully acknowledged by people that debate politics online. Pierre is ultimately subject to the same political pressures.
