When exactly are girls and boys meant to fight this 'natural' tendency? At what age should men and women welcome the other sex in their professional teams, for instance, when they are more comfortable with persons of the same sex?
I also have an 11 years old treaclesoda who is developing much faster than her peers and finds the chit chat about boys who don't reach her elbow unbearable. She wanted to play football with the boys at school. She was either not allowed or the ball was not passed to her. My son, who is 9, explained to her that boys prefer to play with boys, but if she became real good, she would be probably welcome, because wining was important. Does it sound familiar? You need to be good to be part of the boys' club (and I guess vice versa). She actually joined a club, trained with her father and she is decent enough to be an acceptable player now.
As a migrant, I accept this society and try to adapt to it the best I can. My children were born and raised here. I will not do them any favour imposing my nostalgic view of a society where sex segregation is not so widely accepted, as reflected clearly in single sex education percentages.
I don't have a way of 'fighting' this, but I believe is a suitable topic of conversation in a 'feminist Chat'. It is astonishing to see how many accept the 'nature' argument as valid. Even if it was all about nature (and I don't know a single aspect of social science where the debate nature/nurture has been concluded with clear results) it would be worth debating whether it should be accepted or not.
Using Freudian theories in a feminist forum as an authority puzzles me. Someone with the command of English mathanxiety displays, using personal attacks and drama, reproduces the worst features of the Old Boys Networking many of us try to counter. She could perfectly engage with the argument -no matter how stupid it is on her eyes- rather than humiliation. I read this forum to learn, not to be patronized, nor to see how others are patronized. I get enough of this elsewhere. There ought to be some degree of mutual respect when engaging with other women regarding a totally appropriate issue.
