My experience is also anecdotal obviously, but I am seeing something similar. It really did seem like everyone wanted to show how morally righteous they were, one upping each other with what level of disgust and punishment they could come up with.
Suppuku is a good way to put, something very ritualistic/public about this whole thing. Part of me can't help but wonder if women's national team supporters, who are a very small community, felt a need to be somewhat performative since they are rarely in the national spotlight. Yes, they won gold three years ago, and bronze and bronze before that, but even during the WC the coverage isn't the same -- if they had done better then of course it would have been bigger. Aside from the Olympics, this team gets zero publicity. You can tell me that "Oh everyone knows and loves Sinclair" but the average Canadian probably has a 50/50 chance of knowing her and a 1/99 chance of knowing a second player. I wonder if fans think that they cannot afford to lose any goodwill from the general community so they have to strongly denounce these actions which the general public will perceive as evil since they don't realize that flying a drone over training is not a big deal in the world of soccer.
