This person was in no way trying to present "both sides of the argument" (listening to the recordings of the conversation between her and university officials makes that very clear). Opposing discriminatory, toxic ideologies is not a limitation of free speech. Free speech doesn't mean action without consequence. You are free to share your views but that doesn't mean I have to patiently sit there and blindly listen and politely nod. Opposing that is - in return - my freedom of speech.
