Basically everywhere you look, you will only find resources on how men and women are or should be equal, etc.
Obviously this is NOT the case, from a biological perspective we are a sexually dimorphic species and males are larger. Also, watching animals, most of situations show males leading (with very few exceptions and sure enough in those exceptions women ARE larger).
Can you point me to other texts where it was also argued that women are NOT equal to men?
What a mystery you have on your hands. Best of luck with your research.
