Yeah whenever people on here allude to 'what you can't say' it usually boils down to the same few very specific ideas, none of which are particularly secret, original or new. Hell, if you're a tenured professor, billionaire or anyone in a position of power whining about 'what you can't say' I find it hard to take you seriously.
People are getting fired and publicly shamed for statements and actions made one, two decades ago. It’s entirely reasonable to be afraid of speaking something acceptable but unpopular today out of fear that it will be unacceptable tomorrow.
This is a good point. Historical context can be important. You see these issues with people who have been in the public for a very long time (often politicians).
We also saw this with the ok sign where people were digging up pictures of people from years ago and somehow connecting them to using racism through the ok sign. It's challenging for a person who isn't on top of every news story to navigate this time.
