How is sexism that's biologically based not sexism? Just like biologically based racism (not my race) still being racist?
The equal outcome is men and women both being given equal and fair opportunities to express their viewpoints.
If this isn't the case because {reason}, then to me that's justification enough to attempt to redress the issue through modified behavior.
Is there a better solution? I'm being serious.
(At the very least, we don't need to accuse men of being sexist if is proven to be a biological tendency—we should call a spade a spade)
