As many other people have echoed, not in support of Greer but in support of Dawkins, your tuition is payment for an education. That education includes having to listen to people who have differing, often terrible, opinions and learning to recognize why someone has that opinion and ways to deal with others who share their opinion.
And instead of doing that, we're moving more and more towards immediate vilification and avoidance rather than acknowledgement and confrontation.
Avoiding the confrontation entirely solves nothing. If anything, everyone just doubles down on their own opinions, reinforced by the opposing sides unwillingness to engage or eagerness to insult without debate. And having a confrontation of ideas generally doesn't change the opinion of either of those engaged in the debate ... but it does influence the opinions of those watching and listening to it.
For example, calling for a ban - that was ultimately effective - against Greer has actually made outside observers sympathetic to her, rather than transgender individuals. Whereas, letting her speak, but then taking her to task about her comments, would have done the exact opposite.
