I agree, which is why I'm not bitching about it. But it's also kind of sad. I have a young son, and even at 5yo he has seen enough "yay girls!" messages in books and cartoons to deduce that there's something wrong with being a boy.
It's also a good example of the societal construction of concepts like "oppression". The idea that women earning less for the same work is a huge problem, and that men doing more dangerous jobs and dying younger isn't, is a subjective choice we've made. And the problem isn't so much that it's wrong, but that we don't have to choose. We could decide that they're both problems, but we don't. And I think the reason has a lot to do with the heavily-downvoted sibling comment saying, "Well, we worry about the oppressed people, and men aren't oppressed."
