pick any stereotypical differences between men and women that you want.  i'll use the mars & venus analogy: men want to do something about a problem, women just want their men to listen to their problem and understand them.

how are these types of differences helpful? whether you believe in evolution or creationism - being wired so differently from the opposite sex just seems to get in the way.

It is not polite to stereotype.

I actually think the two sexes compliment each other marvelously. I understand what you're saying though. It's the trouble we have understanding each other that gets in the way. I'll admit it! I don't too many admirers. But thank God they are here to think without involving emotion. And thank God we are here to be kind and nurturing. It's a good balance, I think.

Evolutionary biologists (which I do not necessarily agree with) say that the differences stem from two different functions performed by the groups.  The men go out and defend the village, and the women stay home and take care of the children.  If any gender difference can be attributed to this basic difference, they claim that it is adaptive.

In this model, the men want to get out and solve the problem of the enemy attacking, and the women to talk to each other and the children to calm them down.

As I said, I do not necessarily agree with this.  Most of what we see as gender differences are learned from our parents and society.
