I dislike Michigan-
1. I was born, raised, and had a mother who absolutely could not stand Michigan. The yelling and screaming during the game was constant when she was around.
2. I remember the 90s but i also remember 80s and late 70s. The talk that came from the fan base and the players with the amount of ego they had was non stop especially during the 90s. I would just be minding my own business and her comes some Michigan fan with the talk while I was trying to get a nice work out in the gym done. I will never forgive or forget that EVER.
Your points are valid for recent times about support for our conference. The one point I think you miss is before the recent influx of conference strength over all it was about individual teams. You could look at the SEC and basically say it has been Alabama and everyone else with a sprinkle Auburn, LSU and Florida (not so recent).
Michigan and Ohio State is a true rivalry and will always be that way. you can't change how generations have felt about each other on both sides of the rivalry. That is what makes it great. That is why you have fans that can't for the life of them root for Michigan it just won't happen and I am on that side even though you make valid points about recent times. Perhaps that might change over time but for now i still can't cheer for them.
