Bullets and Genderism

Don't ask how this came up (bets on J. asking anyway?) but I was talking with someone about donating organs that would kill you for certain people. As in, if two of my kids needed a kidney to live, I'd give them mine even though I can't live without them. It devolved into who I would give a piece of my liver to if I was the only immediate donor...

...and then it got into the mad gunman brandishing a weapon. I would automatically step in front of any kid (even J.) and almost any woman to shield them from potential bullets. I wouldn't automatically shield a man, even a close friend.

Is that genderism? In our day of equality, should I give the wackjob a shot at the women so they can feel equal? Or should I step in front of the men, too?
