There are now two recent cases where a code of conduct at a Canadian university has come up against freedom of speech.

The first was the comment: "You know this is your 'Master,' eh? Do you feel the lash?"

The second was the comments: "privileged white people", "At this point, f*** you all" and "#whitefragilitycankissmyass."

One of these two is being defended on the grounds of freedom of speech, the other is not.

Why?
