Popper would not have approved anything that happened in that cancel discussion.

Popper knew things like forgiveness, not taking single statements out of context, not reading too much into statements, not misquoting people and much more.

Please do not associate Popper with mob justice. He would have despised the mob.

Written in 1945, literally as a reaction to actual Nazism.

Now used as a cudgel to intimidate and harass everyone who does not follow the party line.

Often the harassers profit financially from their bigotry, which makes them gigantic hypocrites.
