In my experience living in a Football crazy country, Football fans’ almost invariably secondarize moral or principles (in they have any) to their love of the game or whatever team they’re fans of.

I really don’t expect anybody but a handful of people to boycott the World cup as a question of principle, though given the stories coming from there it’s possible that a sense of self-preservation will see many people refrain from going to watch games in the US, but that will be purelly driven by selfish reasons rather than “taking a stand for what is right”.

Football is one of the greatest sources of tribalist identity around and for most people tribalism sits above any and all moral, ethics or principles (as is obvious for example in how MAGA types are defending those Pedophiles who are “chiefs” of their tribe, or how many people take their moral stand on the Gaza Genocide from whatever their favority party leaders say, rather than it being purelly based on the inherent morality of the actions commited there).
