Well, it equals authoritarianism. So you are against banning words and silencing views on the internet and in media opinion pieces? You are against banning far right speakers on campus?
It depends. Certainly right wing speakers should usually not be banned on campus.
ALL campus speakers should be screened to be sure there is something to be learned from them. That is why ANYONE should be screened before being allowed to speak on campus. If, for example, the grand dragon of the KKK wanted to speak on the campus he should have to be able to show that he is offering something that enhances the education of the students. I think he might be able to do that. If on the other hand, a fundamentalist Christian wanted to speak putting forth a Biblical argument for banning abortion I believe there would be little to be learned from that. That person might be excluded. Campus time though is valuable. There is not unlimited time to allow anyone who wants access to students. Further. If I am to have a speaker come to my class I would have to show that he/she is valuable and enhances the goals of the class. It would be wrong, for example, to have an astronomer speak to a Public Health class unless the big one is headed our way. (Then I suspect a brief recess may be more to the point.)
The internet is another thing. It is comprised almost entirely of privately owned domains. They should no more be forced to put something on their internet site than you should be forced to put an Obama political sign on your front lawn. Some sites may feel that they have an interest in allowing diverse opinions. Others not. I would not allow a car dealer so advertise on my consulting page. (Or worse. A child molester, lawyer or anti-vaxer.)
You see how complicated your "zinger" is One Degree?
We live in a time when "Stop shooting our Kids" is considered a liberal talking point.
Ronald Reagan was surrounded by Secret Service agents when he was shot. If he had an armed math teacher?
We go high. They lock up children in cages.
