The fact that people invest so much emotional energy in forming group-centered identities tied in with sports teams is a major tell regarding its conformist toxicity.
I'll say it again:
Sports models war like nationalism on a smaller scale. It is patriarchal violence played out under the rubric of supposedly civil public events.
Ask yourself why riled up sports fans collectively, violently tear shit apart and fight in the streets after a sporting event.
It feeds the same war like impulses.
