Baloney. What we have is a culture that has largely undermined the concept of constructive and well structured argument. One should read the exchanges between friendimies GK Chesterton and George Bernard Shaw. They respected each other and were friendly but if you read their output about each other they would be fired today. Why?
We are pansies.
We assume, wrongly, that argument about ideas and even light jabs at the person are tragic. They are not.
Worse we have enshrined that into law in most places with "hostile work environments". Some ideas deserve to die and you only discover that through _vigorous_ debate.
Do we have to be pricks about it? Probably not. Should we fire pricks that are often right? Absolutely not.
