I understand this reading of it, but if you look at some of the response from UofC’s former student body presidents and others who deal with their PR department, many are interpreting it as a deliberate, PR move from an administration that has come under fire since 2014 for its failure to properly adjudicate sexual assault cases. If it was a simple legal liability waiver, more schools would be doing it. But UofC prides itself on being an intellectually rigorous, tough environmet, and has a documented history of not taking students’ claims seriously, so this is a bit more grandstanding than that. Also the language of the letter is intentionally provocative in places. “So called ‘trigger warnings’” and conflating a lack of safe spaces with intellectual freedom, etc. If they wanted to issue a waiver, they could have done it in a much less attention-seeking way.
