But if there aren't too many of them or they really make us mad, we'll start throwing some punches. Street fights are not really safe anymore. It is probably only reasonable to fight with someone you don't know if your life is in immediate danger. Even then you might be better off trying to talk your way out of it first. You are at some risk depending on who you decide to fight with.
Some little guys are vicious fighters or use weapons.
It is reasonable to expect to be safe without being a victim. See how some teenagers get out of street fights. If you decide to lose your temper or the other guy gets your goat and makes you lose your temper it is hard to think straight.
