Similarly, Most of my friends and I tend to have roughly equal sets of male and female characteristics.

The only real difference I see between some of my male friend's argumentativeness and my own passivity is that they have times where they will admit that they are just itching for a fight, whereas I will not argue unless there is an issue, it affects something I care about, and I know how to fix it. Otherwise it's just people shouting at each other, which is rather unproductive and I have better things to do with my time.
