My concern is that any disagreement with or dislike of some aspect of the culture will be taken as gatekeeping by those who disagree with the disagreement.
Using my hockey analogy again, if I meet some people who are considering becoming hockey fans I don't see it as gatekeeping when I tell them they're idiots if they decide to cheer for the Leafs. A Leafs fan, however, might call me a gatekeeper for saying just this.
Thinking about this some, I think intent plays a big role here.
I am not a sports person, but I'll use the Ohio State/ Michigan rivalry because I know it. If I am walking around a store and see my friend dressed up in a Michigan Jersey, I might call out to them "Hey, stupid michigan fan, your team sucks" We are friends, we probably rib each other constantly, we are not intending anything more than to make each other laugh.
If I am walking through the store and see some random individual in a Michigan Jersey, I am most definitely not going to call out "Hey, stupid Michigan fan, your team sucks." Because I don't know them, I don't their personality, I don't know if they will take it as a joke, or if they will attack me because I'm insulting them, or if they are supporting the team for a highly personal reason (would feel real good to tell the mother of a player that her son sucks at football, despite being a professional, right?). At the very least, I'm being a jerk to this person I have never met. And, is that really the impression I want to give them of myself, and a team I like?
And, so I see your post. I feel like, in reality, you are saying someone would be an idiot to cheer for the Leafs because you are leaning into a rivalry, and culturally, fans of those two teams snipe at each other. But, if I am outside of the context of understanding sport team rivalry's? Then it just comes across as Canuck fans being judgemental and unaccepting of people who don't agree with them.
This isn't about telling people they can't rib each other or have opninions, but about making people aware that sometimes other people aren't in on it, and out of context, you are not sending the message you intend.
