Charges against the left-wing, feminist activist Bahar Mustafa, for ironically tweeting #kill all white men, have been dropped. Those charges — sending a communication conveying a threatening message — were ridiculous and inappropriate. It seems that the campaign to defend Bahar, and arguments in favour of free speech have won out. That’s good. The decision should give us confidence to debate the politics of, and campaign for, a generalised defence of free speech against institutional, state and other forms of repression.
