It's completely missing the point to not see why Canadians would be happy with beating the US regardless of their level currently, especially with the narrative a lot of fans are still spinning and looking down on Canada with. Beating a rival at any point is something to celebrate, especially so when it's been 35 years.
Pointing out that we like some of our players more than the US players, and that we think they're better, doesn't amount to jealousy. This happens all the time not even among rivals; when it does have to do with rivals it becomes a point of pride certainly, and especially after the respective performances in the game that is the point of discussion it makes for some fun banter.
There are still relative levels of success that can be celebrated. It's not 'world cup contender or go home'. When you're a country on the rise and you beat or surpass a team that has historically been significantly better than yours I don't see where anyone else can get off telling you it's nothing to celebrate or be happy about. These are the teams that you'll be consistently competing with just to have the chance at competing with the real world powers anyway. So yeah, down with the USMNT and up with the CMNT; long may this shift in power continue and last.
