As the top post says, White would probably agree with you about the struggle session. But there is room for a wide gulf between a joke leading to a struggle session and "other people people saying mean things in response to your speech". The category potentially covered by "cancel culture" is too broad, and failure to dig into the details and trade offs is at best unserious. At worst, it's a dishonest way to use norms at one end of the spectrum (let's all take jokes in stride) to defend norm-breaking on the other side (Milo should get invited to university stages even though he uses them to bully individuals).
