Soooo, that begs the question - why do you continue to torture yourself (and, by extension, us with your oft incoherent incessant bit(hing)? Serious mental health issues (as others have alluded) would be my first guess.
If you have no real connection to the university (beyond thinking the football team was cool in the 80s) and you really do feel the way your ****** belching posts make you sound (ie the unending disrespect for everything about the university, it’s students, alumni and faculty, “suntan u” etc...) - again, why are you still here? Just leave and come back when the athletic department is operating up to your standard. You’ll feel better about yourself and no one here will miss you - win win.
That said - there are plenty of fans that aren’t alumni (more than are alumni, I’m sure) and nobody has a problem with that. Cane brethren should be all welcoming and all encompassing. But you, clearly, are no longer a UM fanatic.
