You are just being a disingenuous. Dartmouth forced the cancellation of the event by adding insurmountable roadblocks. If the original logistics had been allowed by Dartmouth the event would have proceeded. Why do think it is justified that Dartmouth limits the event to students only when they had previously said it was okay for the public to attend? Why do you think it is acceptable to screen questions? Why would they want to insert an unaffiliated speaker ahead of the event? None of that makes any sense unless you look at it from the perspective of wanting to force the event organizers into not coming.
