I think this is an example of double standards. My impression is that women are more often mocked for gender related actions (cleavage, short skirts, tight pants, aggressiveness, crying, and spreading their legs) than men. I am glad Hillary raised this as criticism.  Blame me if you must, but the image of a man facing the cameras from a sitting position with his legs spread wide and his long dong tie hanging down in front of his crotch is actually rather comical as it is sexual. For some women, it might be sexually aggressive.
This sort of stuff is in the eyes of the beholder, and that is what I behold. Others may say people are too sensitive or just criticize women for displaying secondary sexual anatomy. I don't think the issue can be resolved, but I am glad Hillary brought it up.
