Some women make good leaders, some don't.

Some men make good leaders, some don't.

But one sex aren't naturally better leaders than the other. Given the same opportunities, training and experiences both are equally capable leaders.

You may have had many experiences where one sex is a better leader than others, but that doesn't mean it applies to the whole human race. The number of people anyone has worked with is a minuscule percentage of all the people in the World.

And if you consistently find you don't get on with one sex at work, perhaps it's more of a refection on yourself!
