You're at a disadvantage because your arguments have to make sense
After 200,000 years of modern man evolution it is hardly surprising there are differences between men and women. It is not an important issue anyway.
There are some
tendencies towards differences but with the exception of a few biological characteristics that can be objectively measured (e.g. height) it's very hard to get any solid information on which tendencies actually exist. For any that do, it would usually be impossible to seperate nature from nurture (again with the exception of those few objectively measurable biological characteristics).
On top of that, there's the problem of interpreting the effects of those differences and of common biases affecting that interpretation. For example, it's usually possible to tell an adult's sex solely from simple physical examination of their brain. That doesn't mean the differences have any effect. Also, the degree of difference has been wildly exaggerated into the idea that there is such a thing as
a female brain and
a male brain because that fits the fashionable prejudice that men and women are inherently and significantly different. Direct studying of human brains shows otherwise - all the people studied had brains with some "female" and some "male" characteristics because the belief is wrong. The only proven tendency is for men's brains to be bigger than women's brains. Which, to belabour the point, has no known effect.
It's not "men are from Mars, women are from Venus". It's "humans are from Earth".
