Except that it's actual nonsense. Not long after WW2 the congress tried to ban comic books for spoiling the youth,just couple decades later people were holding public protests against the Simpsons, and the first TV show to mention the word "period" was met with similar level of protests as if that's something dirty and unspeakable.
No, it's the exact opposite - "back then" people were far more fragile and sensitive and doing or saying the wrong kind of thing could have serious consequences on your life.
Those are examples of a morally conservative society, in which a Judeo-Christian value system was in place, and when there was a stronger emphasis on conformity. I guess the sensitivity was in breaking those rules. In those times too, however, children were taught "sticks and stones may break my bones, but words can never hurt me".
You are both right, in some ways we have become less bashful about certain aspects of life, but also society today is a bit more particular about some things. It is no longer enough to disagree with someone, you must destroy their will to continue.
