This is where you're wrong.
Two of my children just graduated from college, so, I've witnessed the indoctrination first hand. Thought police have infiltrated colleges telling our children they should be ashamed of their upbringing because they had it easier than others, their opinion doesn't count because of who they are. Should they utter a conservative thought, they become outcasts at their schools. Dialog between opposing opinions have disappeared on most college campuses. There's no longer give and take.
Valparaiso, like many schools, has students who are taught that they are responsible for righting the sins of their parents and grandparents. Activism is their form of contrition, it gives their lives meaning. Valparaiso's students forced the hand of the University and it's not accidental that this is happening everywhere. There are many occasions where it is necessary to change mascot names, however, Crusaders isn't one of these occasions.
Next up - names to be erased: Pirates, Vikings, Colonels, Buccaneers, Saints, Pioneers, Patriots, Minutemen, Trojans, Spartans, Blue Devils, Volunteers, Rangers, the list goes on.
