I have a new favorite schadenfreude post from RCMB
It's because they act arrogant. People that went to UM think they are better than others not because of anything they have done in life, but for the sole reason of where they went to school. Because it sees itself as an exclusive community, UM is a breeding ground for arrogance and entitlement. Somehow the non-affiliated fans think they can get a piece of that experience by rooting for the school; that they too are part of an exclusive community. Non-affiliated fans see UM as the superior school and root for UM in an attempt to boost their own self-perception at the expense of others. The best part is that UM is such an exclusive community they have the same contempt for the non-affiliated fans that they have for everybody else. People that root for UM but did not go there and otherwise have no connection are absolute fools. MSU is the state's land grant school. Part of MSU's mission is to serve the state and its people. MSU is the true university of Michigan, and CMU and WMU are more universities of Michigan than the University of Michigan. The non-affiliated fans are too dumb to see this, or just think rooting for UM makes them part of something special.
It is hilarious this tool actually believes MSU is "the true Michigan university." The delusion and inferiority is high in this post.
