For the love of all things good and holy, please spare us your lectures on morality. Nobody cares.
It does not make anybody less of a fan because they don't share your holier than thou views on how you believe we should all love and support rival schools.
Reality: That is not how it is. It's not that way for them, it's not that way for us. It's not that way for the California schools, the North Carolina schools, the Virginia schools, Iowa schools, Alabama schools, Georgia schools, or any major programs that come to mind.
If tragedy struck, rivalry is laid to the side, but this isn't some kind of matter of death and destruction, this is a rival school getting caught not playing by the rules (ironically, after saying that UK doesn't play by the rules for years).
If you don't like it, leave. It's simple, but don't come here to lecture any of us.
