I have spent the better part of 30 years in journalism misattributing to Voltaire the idea that I would defend free speech to the death, even if I disapproved of what was being said (it turns out it was a summary of Voltaire’s views by his biographer, Evelyn Beatrice Hall).

Yet, events since October 7th have revealed that there are, or should be, limits; that people cannot say things that incite real harm to others or society at large.
