In a perfect world, being a decent human being would not only not be that hard, it would be enough. Unfortunately, there are enough women out there that simply are not decent that steps must be taken to protect oneself, same as with men of the same general odor.
As the situation stands now, in a case of 'he said, she said', the woman is more likely to prevail than the man. And women will lie.
Oh come on. ~People~ lie. And there are people of both sexes that are both good, and bad. To paint one sex as having a 'lock' on decency or lack of it is the EXACT gripe men rightfully have over the modern feminist movement. You're attitude is exactly what men hate about Maureen Dowd, and no more right when you do it.
