On one of her CDs, Ella Fitzgerald sings a famous Irving Berlin song that Fred Astaire sang to Ginger Rogers in the movies. Now, it makes no sense for a woman to be singing that song. But I've heard Ella sing a good number of songs that were meant for a man to sing. I have never, ever heard a man sing a song that was intended for a woman to sing. It's not done.
Feminism is a buttress for true masculinity.
That there isn't one highlights the difference between the situations of the two genders. Feminism is the best thing that ever happened to men.

We spend so much time posing and fronting and putting on incredible, ridiculous acts. Feminism is at the cutting edge of nearly all major intellectual disciplines.
