For me, this post is not doing any favors for the "women's experiences are fundamentally different" camp. Most of these sound like stories from my own life. Of course, "Why are your characters always girls?" is probably a harder question for a boy than a girl.

I'd guess these mostly work as stories of "growing up geeky".

The only ones that didn't resonate were the last one about not playing M:tG anymore (probably since I've never stopped appearing like a geek) and the "Star wars characters are mostly male", which does seem worth mentioning.

MLP:FiM is probably a good available example of the reverse phenomenon. The positions of power are occupied by females. There are very few male characters (though a significantly more even ratio than Star Wars), and they seem to be shoehorned in as male stereotypes. I suggest male readers ruminate on this aspect of the show until it seems a bit disturbing. And then notice that females can experience this when watching most things.
