It's a fine line between protest and cancellation. One one end of the spectrum, you've got people being harassed, doxxed, and coercively fired for what amounts to a social faux pas - like having made a borderline racist remark over 10 years ago as a child, or having expressed a sexist sentiment more than 20 years ago (the guy at Boeing). On the other end, you've got a person with a history of enabling pedophiles to access children, in a position that would allow them to extend that access to the pedophiles with which they personally associate, which seems like an actual real danger to children and youth.
To me, one end of that spectrum seems like absurd overreactions... and the other end seems like appropriate action. There's undoubtedly a lot of gray area in between where it's uncertain and people have differing views.
What has baffled me a bit with this thread is that there are a whole lot of people who don't seem to see a gray area at all, and who seem to feel that all cases of such actions are perfectly fine and acceptable. That worries me, from the perspective of a well-functioning society.
