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?
Yes, it does. You are trying to make a very generalized argument that women are not equal to men. How do you propose to do this given that, while there are similarities, there are also vast differences between the members in either group? I would suggest that you are attempting to paint with too broad of a brush.
What is your definition of equal?
