So a Sparty made a video about the fans of Michigan (and other schools) that have no connection to the school outside of fandom.
Having difficulty embedding it so... https://www.youtube.com/watch?v=46MsGQFrzPE
His thesis is that only students have earned the right to say "we", which is disagree with because only players truly have that right. Also only alumni are able to build that close of a bond because of the shared struggle financially and emotionally.
If there is no connection to the school you should be a professional sports team fan instead.
I am a huge supporter of sidewalk alumni myself but I was curious what other people felt about the issue.
