Ann Coulter plans on making a Human Rights complaint because she feels her rights were violated with respect to the cancellation of her talk at the University of Ottawa.
It seems there are two talking points, here. Was it threatening when the provost wrote to Ann Coulter, saying "promoting hatred against any identifiable group would not only be considered
inappropriate, but could in fact lead to criminal charges."
And, is it a violation of the right to free speech that the protesters were successful in getting her speech cancelled?
Well I don't know how Canadian Universities are but in the United States, any university is a business and not local, state, or federal property. A university in the United States can deny anyone they like from being on their grounds for any reason at all. So at least here it would not be a violation of her rights.
Ann Coulter is still capable of speaking anywhere she wants. I'm sure if she wanted a permit to speak for free in a public space at the University of Ottawa, she could obtain it. Student fees though pay for the speakers at the school. If the students don't want their money going to her, they should be able to say that's not what they want their money to go toward. Ann Coulter has a right to air her ideas--she doesn't have the right to any venue she wants. If those who run the event don't want to pay for her to speak, she can't force them to.
