I'm reading that you feel like constructing and attacking a straw-man version of my position ;)
The thrust of the Guardian article was that freedom of speech is no longer valued at Universities in the UK, or at least, to no-where near the level it was value in the past.
Specifically, the practices that people are advocating to use against Neo-NAZIs are, right now, being used in Universities in the UK and elsewhere to shut down political dissent.
That's what I meant by 'this is already happening'.
