If you really want to see how far we've come on sexism, checkout original Battlestar Galactica which I happened to be watching the other day. Original Starbuck was a male, two timing womaniser and, oh wasn't it so funny. (Not). And then, during the initial Cylon attack and destruction of the colonies, Athena, a senior military female character burst into tears and ran off, leaving her post. Not forgetting Cassiopeia, a "sociolator", wink, wink (Compare and contrast with Inara, from Firefly).
Shameful, blatant sexism from 1979.
