So, I was working behind the front counter at the store, minding my own business and putting stuff away.  Someone else was on the register.  A small group of women had all shopped together and were now checking out together.  One was telling a story about an admittedly dumb-sounding thing her husband had done.  They all had a laugh and another woman in the group actually said, “Well, what do you expect from men, they’re all so stupid.”  They all laughed even more and expressed their agreement.  Fine, have a laugh.  But I cannot escape the idea that if I had said, within earshot, the same thing about women, I would have been instantly pilloried for being a misogynist jerk.  They probably would have wanted to complain to the manager.

My point is, if you want bad behavior to stop, start by policing your own behavior.
