Boise State is a regional rival and Notre Dame is nationally relevant. Why should such a post be ridiculed?

If you don’t like people who post about other teams in the generic college football category, then you can block the category or block the person who posted. Whatever you’d like. Or if you see from the headline that you’re not interested in the post, another idea could be to ignore it and move on to the next post to see if that grabs your attention.
