The fact that we do not have essential gendered natures

I hate most that it has become common sense to essentialize female nature in absurd ways. For instance, recently a Canadian anti-bully activist came here to teach Australian school children how to avert bullying. She said she wanted to focus on girls because they were bitchy and gossipy and employed passive aggression, spurred on by their mothers. Now, fine and good. perhaps this is so. But in my day -- and, of course, in a very different culture -- that was not "female nature" at all. Rather it was to be naughty, mischievous, cheeky and yet polite. There was no rivalry and we just enjoyed the pleasure of companionship. Actually, you can see the same kinds of attitudes expressed in the British nursing drama, Call the Midwife.

So, as late as the 1980s in Zimbabwe and the 1950s in Britain, female nature was not petty, bitchy or malicious.
