If you read the article you would have seen that in a 2-1 vote the supposed offended individuals supported the use of the name. This is just PCism run amok as usual.
There were these protests some years ago at San Diego State University, where the nickname is Aztecs. And we heard how Aztecs is demeaning to Mexicans and the memory of Montezuma and all that. They took a vote of students and alumni, and 92% voted that they should keep the name. So the effort to force the name change at San Diego State died out. And they are the San Diego State Aztecs to this day.
