Most Americans will try to ignore an idiot making insults, or may throw insults back. Some will call the police, and a few will resort to violence but almost no one will kill. Only crazies will kill innocents over an insult here.Excuse me this question,if your neighbor do insult you personally,
What your responce at the moment ?
will you say to him,wait me for a moment i'll bring a policeman,
or your honor won't make you able to wait for moments.
i am just try to understand the relation between insult,anger then violence.
which in your case,it may lead to boxing if not asking the police help.
