There are only a couple of reasons I can think of for a woman to shave her legs: 1) some medical issue; 2) to fit in to social memes. The problem with fitting in with social memes is that they exist more or less in a moral and consciousness vacuum. To "fit in" without abandoning personal judgement and reason is all but impossible, frankly, unless society just happens to be functioning in a manner which meets your ethical and rational approval. Frankly, society telling women that to meet its aesthetic standards - unconscious and stupid as they may be - they must remove bodily hair is something that does not even remotely meet my personal ethical standards - so I reject it. For each individual person it's really a matter of doing what your reason and conscience dictates. Of course, the sad thing is that for the vast majority, neither thing enters the picture. As I implied earlier, if people actually thought about how and why and when they wish to "fit in", they wouldn't really be doing it.
