As there seems to be a somewhat shrill response from some of the feminists on here I'd like to clarify my own position on the subject as I don't wish to be tarred with any particular brush...
Overall, on average, generally speaking, however you prefer to phrase it, women are physically weaker and smaller in stature than men. That is accepted as fact by pretty much every rational person.
That is why they are separated for almost all Olympic events and why men hold the most world records in those events, and why professional sports are not unisex, including combat sports et cetera et cetera.
Given the physical nature of fighting then logic dictates women are at a disadvantage. There is also all of human history to back it up.
There is nothing remotely sexist about any of that.
It doesn't mean that there aren't exceptions, or women can't fight, or some women can't beat some men, or that some women couldn't beat the crap out of most men. There must be thousands that could wipe the floor with me!
Whenever there is a distinct mismatch in size and strength in a fight, the smaller person has be of a higher skill level, smarter, or both in order to win.
If anyone still thinks I'm a terrible misogynist for recognizing these facts then please bear in mind I am a student of Wing Chun which we're taught was designed by a woman in order for a smaller person (woman) to defeat a larger, stronger opponent (man) and does not rely on physical strength in order to do so (smarter)
