> It can be read negatively against boys or negatively against girls so why post it?

This part I really do not understand. The undeniable fact that boys and girls are different in several aspects does not make either superior or inferior in value or in dignity.

On the other hand, anything can be read negatively if you put enough will and effort into it, as so many people around here demonstrate.

How about being a bit more constructive in our criticism?

> This comment explains absolutely nothing

Sure it does. Boys and girls are different. Hence, they receive different treatment, which the OP was originally befuddled by.
