I agree careers get ruined more often over silly things now, but its not anywhere close to a modern issue. People have been getting some form of “cancelled” for pretty much all of time, sometimes for a good reason and sometimes for a bad reason. If you really live your life in constant terror over the idea, maybe you should become self-sufficient and move off the grid. Thats kinda the only solution to the problem. People are social animals and social animals sometimes make stupid social decisions such as “cancelling” one another and its just kinda unavoidable.
