If you can not see he is a promoter of the "hawk" brand, then there is not much I can do for you. ISU is behind in the arms race of college athletics more so because of promotion off of the playing field, then the physical play on it. It is likely he does little direct monetary harm to ISU, and even if one chooses to ignore the externalities, it is certainly logical for an ISU fan to not support him based on his lack of respect for ISU. It is not that he is a hawk fan, it is the fact that he is a "tavern" hawk.
I do not support people based solely on their location of origin.
