I would probably worry about being attacked more. Although female myself, I've known many more women than men that truly do think with their emotions and whims and not their head.  Also, it has been my observation that women think they have to work harder to hang on to their powerful positions, and that is why they can come off as a bitch, but it can also cause them to make unreasonable decisions. I can see decisions being made based on their emotions without regard to what their military commander recommends. I think this trend of fickle women is a modern trend because women, based on what is allowed in society, have many societal safety nets (ex. alimony and child support) and have been granted the rights of men without any of the responsibilities (ex. women aren't expected to learn domestic skills, but men are still expected to be breadwinners). They aren't forced to make many critical decisions, and their decisions largely don't matter  because everything will be okay .    As far as I understand the Middle Ages, a queen would be brought up differently than someone from peasantry or the middle class, but in the end there were expectations for each and not fulfilling them meant they would be executed, ostracized to a lower social class, become homeless, die of starvation or disease, or be forced by circumstances to become a prostitute or nun. Women in past times had to be competent in whatever it was they did and their decision-making ability because the stakes were high.
