Before we go into this whole chauvonist argument and etc, let me just go out on a limb and make a bold statement: there are just as many stupid, immature, outspoken women in this world as there are stupid, immature, and outspoken men.
I've at one point or another in my young and soon to be CEG-flamed life argued to the affect that most woman are less mature than men in regards to common sense, but even to someone as outspoken as I it would seem that this statement is quite unfair and presumptuous.
I would still rather contend that for the majority, men gain a greater dose of common sense faster than woman as the typical "naturally stronger, less beautiful" (ha) nomenclature usually involves us having to grow up faster, get a job, face the reality of loss and gain sooner, and experience the harsh reality of life in a much more hauntingly painful way; in the grand scheme of things, however, and I'm sure many of you here would fail to agree with me, women are generally the more responsible and sensible ones.
Responsible and sensible

... Their loss I suppose
