To throw yet another piece into the puzzle:
A few years ago I had a class where we went to Comic-con to do an anthropolgy study. It was a super fun class, and I decided to tackle an easy subject "Women in Comics" because I'm crazy. However, within the first few days I had to broaden my topic to "Gender in Comics", because I noticed a few things about the male side of this whole equation.
The biggest moment for me came from an old comic writer (wolf something? I think he worked on Vampirella) where he shared a story of a comic series he tried to pitch to his boss back in the 70's. The pitch was essentially an all-woman team of superheroes, fighting crime and stopping villainy and doing all the things superheroes do. His boss immediately quashed the idea, not because "women can't be heroes" or something stupid like that. It was because 70% of their readership was male, and "boys won't read something like that, but girls will read anything".
Now, of course, girls "read anything" because they weren't really given a lot of choice in the matter, but it was that first part that struck me. Most of my favorite characters in literature are women, far outweighing the men, and they are generally pretty awesome people, but when I was younger and still a fan of anime there were a lot of shows I loved that I never talked about with anyone, because to a degree I was ashamed for likeing them.
The big one I remember was "Maria watches over us" which is essentially a slice-of-life story about some girls in an all-girls catholic school. Nothing much happens, there isn't a lot of action, and it is simply how the characters interact with each other. Everything told me this was a show that as a boy, I was supposed to not like it, but man did I love those characters and how some of them were very composed and traditional and the others were goofy and silly and it was a great show.
Things have been changing slowly, but I imagine it is still the case that a boy who likes "girly things" like those sort of shows or the Bachelor or who knows what, is still going to be pretty ruthlessly mocked and derided.
Though picturing it, it would be moslty men who would mock them, and that is pretty indicative. We police our own gender, not each others, as a general rule of thumb. And I wonder if taking a more multi-faceted approach to equality in some areas would yeild better results than just focusing on one gender or the other.
Of course, striving for gender equality while another section of society is just working on blowing up the whole concept of a gender divide is kind of difficult in its own right.
