If you want to generalize, middle-aged women, regardless of race, seem a lot more defensive and angry than men. I think once they hit that certain age when they're no longer the focus of attention, they become demanding and downright nasty. Men don't give off as much attitude since a) they never were the ones getting all the attention, and b) they have to answer for everything they do.
Think I'm wrong? Go work in retail or customer service. See who does 90 percent of the whining, bitching, loud complaining, and generally obnoxious behavior. it's not senior citizens, it's not teenagers, it's not young women, it's not men of any age. It's the middle-aged females who make the most noise and turn every molehill into a frigging mountain.
