The reason I take it for granted is that at Grinnell most people are aware of it. I'm going to write a little paragraph about it as well. First, the distinction between gender and sex is important. Sex is just about what body parts one was born with. People can be female, male, or hermaphadidic.
Gender is different, the terms man and woman and masculine and feminine describe gender.
When we say women are more emotional or like shopping or are nurturing or like chocolate and men likes sports or drinking beer or having sex or driving fast cars or can't express their feelings, we are describing gender. Basically anything people tend to draw up as a difference between the sexes that is not biological, is gender. Okay, so I don't believe that little baby boys are born with an inherent greater interest in sports, sex, and cars, while baby girls come out ready to go shopping and gossip about the neighbors. But its not that males are born less emotional. My little brother was a much bigger cryer than I was.
