I've seen the usual suspects on Twitter say things such as, 'Salman Rushdie has principles, J.K. Rowling is just a transphobe.' (i.e. the person I agree with has principles, the person I disagree with is a bigot.) They are saying this without irony. The Rushdie stabbing hasn't caused a moment of self-contemplation for the cancel culture mob.
There's also been a lot of, 'Why are people shoehorning in J.K.Rowling on this? No-one's killing gender-criticals over trans issues.' (Well, they had a go at killing Ralph Knibbs and Dave Chappelle, as well as violent attacks on people like Julie Bindel, so I don't think we can feel too confident about that one.)
In general, it feels like we're living through a really bad time for freedom of speech and artistic expression.
