Morgan - your characterization of women isn't necessarily inaccurate, it's just that your use of that characterization as a generality describing ALL women, or even a majority of them, is frighteningly obtuse.
Based on women I know, you're description of a female's failings seems to be taken from observations of characters on "Desperate Housewives".
Assuming for a moment your characterization of "all" women was valid, and you made it this broad by your follow-up assertion that women shouldn't be President, I think your deductions would be accurate.
There has to be someone on which your generalization was based, and I realize it probably isn't you. I don't think we're in some sort of competition to get more women into positions of power. I do however think that there is a "right person" for any given job, and their gender plays an insignificant role in how they will perform.
Condoleeza Rice has proven that gender is irrelevant when it comes to dealing with even the most pent-up and backwards misogynistic nations on the planet. Given that, what you seem to be veiling is an assertion that women have an innate inability to control hormonal urges on a monthly cycle. To that, I can only say you need to broaden the demographics of your female friends and associates.
P.S. Nobody patted you on the back and said "Nice job putting together a coherent thought!" because it would be demeaning and sexist. You can't have it both ways.
