Rubbish - Pinker is exactly the person that should be protected and there's no need to 'rehabilitate him' from anything.
Celebrities of various kinds interact with each other, that's how that works.
If you were invited to a conference and the CEO invited you on his plane because you had something interesting to say, and 10 years later we find he was a rapist, do we cancel you?
If you're going to tell me that Pinker was 'on rape island sleeping with teens girls' - then obviously that's another matter, cancel away, but as far as I know that's not the case.
This is exactly the kind of petty, toxic, vindictive posturing exemplary of bad cancel culture.
