What do you say to someone who doesn't believe in feminism because "men and womens brains are wired differently"?

I can't get my head around it. The friend in question is intelligent and educated and not stupid at all, yet spouts this as the reason why feminism, why equality doesn't work. Where she sees scientific and historical evidence to support this, I just see opinions. Apparently because men are the typical hunter gatherers and women the nuturers, we should just accept that. I'm just getting so sad listening to this.

Anyone got any tips one what one says to someone so mired in this belief???

I didn't mention future environments, so it is incredibly bad form to put it in quotation marks to imply that I did make such a remark.

I will leave you to your straw man arguments, because this is really a waste of my time.

MillyR - sorry was typing fast, the bit I should have quoted was "You could believe that this species was able to adapt through having different behaviour in different environments" ... Which I took to mean you saying colour vision developed because it would be useful in all kinds of different situations. Maybe that's a straw man or I misunderstood what you meant.

Anyway it is a simple enough question - what do you think was the advantage conferred by colour vision in primates and early humans?
