That's blasphemy. You are only allowed to think that physiology and millions of years of different evolutionary developments are totally irrelevant, and that this is the year zero: all divergent cultural and historical choices between the sexes were only and solely the result of oppression and discrimination, and sexes only differ in having different reproductive organs.

What if that same excuse has been used as far back as you choose to look for all sorts of discrimination? It's not that it can't possibly be right, but it's a hypothesis to be forced to, not to grab and promote above all others. And we just haven't been forced to it yet.
