The way I see it
Getting into a fight as a male, is almost a rite of passage
I'm not saying that you should go looking for a fight, if you can avoid it, than by all means do so, (especially if you are of age of being an adult)
getting into a fight as an adult just leads to all types of bullshit, but then again if you're life is in danger, do what you have to do
but sometimes, especially if you are going after something, someone else wants (hopefully it's not a bitch), or sometimes someone won't like you because you are successful at something and they're hating
Getting into a fight coming up isn't a bad thing
You learn how to defend yourself, that everyone won't be your friend, some ppl just plain don't like you and that's okay, and it's definitely an ego boost if you whup his ass and or if you whup his ass and no expected it
Again this all falls on the character of the person and what's your temperament during tense situations
the chances of a female fighting in this world are less, compared to a male getting into a fight, because of the testosterone and competitiveness between men.
Even though we have evolved as humans and as a civilization, that primal instinct of "fight or flight" is always evident
it's just that now a days, its stays more dormant than anything
