Freedom of speech ≠ freedom from consequences.
If I stood in the quad at UCL with a megaphone shouting that vaccines cause autism, would it be unjust if I was removed from teaching courses in biology? If I said on live radio that the Holocaust was exaggerated, could I expect to keep getting gigs as a BBC presenter?
What about if I was invited to give a lecture at another university, and before I did it, declared that gay me cause Earthquakes, and was subsequently disinvited, so I have a right to appeal that?
Ok, what about saying that Churchill vigorously promoted eugenics policies, which is true, but offers a negative view of one of Britain’s most idolised figures, could I be sanctioned for that?
I know these are obvious examples but I’m trying to understand the boundaries. I have the right to be a homophobe or a misogynist, and I have the right to express that. I have the right to say medically or scientifically illiterate things, but employers have the right to fire me.
Once a speaker is invited, do they have rights not to be disinvited? Is that a rule? Say it’s unpaid, so no contractual binding.
