Men don't understand women. Women understand women and they don't like each other. Sadly the female of the species is very looks conscious. They wear makeup and get fancy hairdos and wear outlandish clothes that scream look at me. It is instinctive and part of that goes to judging other women on their looks be it skin tone or the shape of the nose or the length and colour of the hair. Not much can be done about it except to realise that it is common to the human species and try to avoid doing it yourself as much as possible.
