In some cases, this 'cancellation' culture, seems to became wildly over-sensitive, and unreasonably nasty.
Typical examples, are where a prominently successful, publicly well known (in at least some circles, such as sports, music or films etc), is perhaps 32 years old now, and doing really, really well.
Then someone brings up a tweet (or similar), that person made when they were aged around 17 (and perhaps still drunk, after a long late night out), and it was only between their couple of hundred (or thousand, perhaps), followers, a long, long time before they were famous. Where they said something, somewhat racist (or breaking some other, modern day rules).
It then gets published and complained about on the news and / or social media and / or somewhere, and they end up cancelled and / or forced to resign and apologize.
It just seems so unfair, unreasonable and crazy. What use to be called a witch-hunt, perhaps.
