More examples and some strategies...
I have also felt the frustration that the OP feels with regards to how boys are treated. It really came to a head for me one week when I was feeling particularly vulnerable with regards to how people were treating my husband (a SAHD) and my son (a normal, but active boy) AND I came across a letter to the editor in our local newspaper about parents whose baby boy was being refused day care spots just because he was a boy AND on another message board I was on, women were going on and on about how it isn't safe to leave your children to be babysat by teenage boys or by men because they are likely to abuse your kids. I was really worried for what that meant for my child and also what it continues to mean for my husband (e.g. other parents aren't comfortable having their kids come over to play when I'm not home because my husband is a man, which isn't fair to him or to my kids who then have to forego play dates when Mommy is at work).
Anyways, I got so frustrated and mad that I put all that energy into a long blog post about the Bias Against Boys (you can read it here: http://phdinparenting.com/2008/07/12/bias-against-boys/
), including thoughts on some of the myths/perceptions of boys:
Our boys as hyperactive
Our boys as sexual predators
Our boys as violent
Our boys as uncaring
I also talked about the real and perceived differences between boys and girls and concluded with some thoughts on what we can do to help get rid of this bias against our boys:
* Teach our boys to be nurturing - give them the power of emotional intelligence.
* Give them a healthy diet, to avoid excess hyperactivity
* Give them opportunities to roughhouse and wrestle in a safe environment by engaging in physical play with their parents
* Give them plenty of opportunities to play outside, run around, to explore and to use their energy
* Limit access to television and Internet and ensure that materials are age appropriate and do not include images of violence or unhealthy sexuality
* Teach them about healthy sexuality and encourage them to ask questions
* Encourage them to express their emotions and rather than keeping them bottled up inside
* Teach them to respect people, including teachers, women and girls, those that are weaker than them, those that are different from them
