The 1950s, a time of reduced sensitivity. The kind of reduced sensitivity where the military had to be called out to invade states, and put down actual riots, sparked by black children trying to go to school with the children of white parents who were definitely not triggered and not mad.
It's the wild growth of certain sorts of sensitivities that certain sorts of people are finding a problem. Nobody remembers the "good old days" as a time of hedonism, where everybody did their own thing, where beliefs and behaviors weren't policed, and couldn't result in you being ostracized socially. In the good old days, you could not only get canceled, you could get lynched.
