My son is about to start his second year at University and is as dismayed as I am about the student attitude to free speech. he believes that anyone should be able to say anything and is anti no platforming. In fact he gets very upset about it.
he is very clear that there are laws in place to prevent hate speech and incitement to violence or threats to kill - but that all else should be left alone.
he gets into some very heated debates with his friends on this as they accuse him of being right wing etc. Strangely though, they agree to the concept of free speech, but think that people should only say "nice" things about other people and keep nasty things to themselves.
Surely this is how "nasty" people fly under the radar and grow in numbers - if we all pretend these people don't exist they can spread their ideas underground.
Not all students think like this - but a very high number do.
Universities are no longer teaching critical thinking - something has gone wrong.
