I've had folks before say to me things along the lines of "real men fight".
I like to reply that fighting is strictly in the provenance of boys Ė which of course precludes men Ė and that anyway real men have responsibilities they cannot afford to jeopardize by engaging in aggressive and/or criminal behavior.
I, for one, will stand my ground and yet defer any sort of physical altercation until my hand is forced. Because that's what men do.
In other words, I won't start a fight. I won't engage in a fight. But if my life is threatened, I will end a fight.
