Not on this particular thread so much, LadyLaGore, but I don't want to drag anything else into it so I will leave it there.
As the mother to a ds, I feel that men and boys are discriminated against, regularly, through attitudes rather than practical ways. Girls are encouraged to go into "manly" careers, it's seen as a positive when they become engineers or scientists. They can wear whatever clothes they want. Girls are seen as high achievers in schools, and more likely to succeed.
On the other hand, boys tend to be seen as lower achievers at school, especially as the school system tends to be more suited to the style of learning that girls often adopt. Many boys learn actively, and there isn't always the opportunity for that in schools. Girls are encouraged to express their feelings, whereas boys are often suppressed and told that crying is "girly". Boys who choose to go into "feminine" careers such as hairdressing and beauty or childcare, or who do things such as ballet, are often supposed to be gay or end up being isolated because of their choices. My dh is a primary school teacher, and has found it very hard to deal with small children because of the common attitude that men are more likely to be a risk to children. It makes him feel uncomfortable in his job. Finally, boys can only wear "boy" clothes - wearing the funky, sparkly or bright coloured clothes that girls wear would make them a target for bullies.
I feel strongly about all of this, because I want my ds to grow up with a wide range of opportunities available to him. I don't want him to categorise things as "boyish" or "girly", I don't want there to be limits on his choices.
Yes, women are discriminated against in many ways. But so are men and boys, through the same ingrained attitudes that help to discriminate against women. There needs to be a large scale societal change, and I don't think that the kind of feminism where all women are right and men are usually in the wrong, is at all helpful.
