You got my upvote. Boys are treated so differently within their own family, daughters given more love, attention and protection than boys. And then you just have to look at the few lines in the article to know how far this problem goes: "but what's happened is, particularly in schools where most of the teachers are women, there's been a general girlification of elementary school, where any kind of disruptive behavior is sinful"
Let's just stick to the facts related to the argument. The article was not about comparing girls to boys except a small side-note about diagnosis ratios and the increasing expectation that children sit quietly at school. Your comment is a non-sequitur about boys being undesirable, which is not relevant to this particular discussion.

2. Also in modern American culture, there appears to be a very strong preference for having female children over males.
