This article assumes a priori that talking to boys differently than to girls is bad, then attempts to substantiate the claim, in part, with references to obvious bullying -- a very different topic. But it overlooks the obvious: that boys and girls are different!

I have two daughters and three sons. I love them all. I speak to them differently because they need to be spoken to differently for them to be understood, and for me to provide appropriate instruction. Contrary to this article's thesis, the kids actually lead with this. As is typical, the girls are more sensitive, and tend to seek approval and understanding. The boys are more rough, need to be spoken to much more bluntly, and view me (their father) as an intellectual companion / wrestling partner, depending on their age. I imagine most parents find themselves in similar situations, and we respond according to the needs of their children. It may not be PC, but in my experience, those needs are often correlated to the chromosomes of the people involved.
