Beyond just a little alarming. Over 40% of the population basically said "We don't want Canada to survive the next four years" with their vote.
No, that's going way too far.
Bear in mind that although you might be focused on this election as a single-issue voter, lots of other people don't share that focus. When there's polling specifically about whether Canada should join the US the positives are in the below-10% range, comfortably into "just crazies and loons" territory. But a political party like the Conservatives have a wide range of positions and people can find them compelling in various ways. Conservative voters also want Canada to survive, they just have different opinions from you on how to accomplish that and what "survival" means.
I'm quite happy that the Conservatives didn't get into power, I think Carney is the right person to be leading Canada right now. But let's not jump to painting people we disagree with as being all a bunch of lunatic monsters.
