Really though I'm not sure why it's so common these days. What I am sure about is that I don't like it, and what I'm equally sure about is that "father knows best" idea isn't any better, for me. I think both types of gender roles can be harmful by pushing the idea that you need to behave like that whether or not it makes you happy. But it seems like a lot of people are drawn to either type of gender roles, with some overlap between them (i.e. male with dominant posturing, but female runs the show), and are happy in those relationships, and a lot of other people try to avoid either scenario.
