Jordan Peterson, the Canadian clinical psychologist and author, has returned to Twitter after Elon Musk rescinded a ban that Peterson was struck with back in June for “misgendering” someone. And what a return he has had! It’s like he never left. As I write, Dr Peterson has posted thirteen tweets in the last hour alone. Such energy! Say what you like about the author of Twelve Rules for Life and Beyond Order, but you can’t deny his commitment.
