You might not need it in parts of the world where life is brutal and violent for almost everyone. But in the Western world today, you do need it. Know that you are under attack. You can feel the attack directly, If other people are around, they will usually have seen and heard the attack too, and they'll agree with you that it was an attack. Often there'll be physical evidence in the form of bruises or cuts, to back up your claim.
Verbal attacks are very different.
And it's often very hard to spot the actual move the attacker has made. We can say any sequence of English words, no matter which ones we choose, in a way that is hostile and brutal. We can say any sequence of English words in a way that is friendly or loving. The emotional messages of English are carried by the tunes we set our words to, not by the words themselves. You may have thought that it would be easy to spot verbal violence because the attacker would be using obscenities and open insults and calling you ugly names.
