I'm arguing that Harvard should be able to use reasonable measures to affect campus discourse, up to and including an outright speech ban if that's necessary, given of course that it is appropriate with existing limitations on such speech bans. (time, place and manner restrictions) You are asking about specific policy that I think Harvard should be able to or not be able to enact. The thing about policy is that it necessarily has a chilling effect. But symbolic actions like this one can send messages without making everyone feel like they're under the gun. Properly tailored, it scares the people that need to be scared and lets everyone else feel safe and protected. I have no problems with the action that Harvard took. They did not rescind all of the invitations of those involved, and exercised good judgment. It was a nuanced and appropriate response to the situation. If you remove the ability of school administrators to exercise judgment, then you're basically tying their hands together and things can rapidly devolve into a cesspool.
