why is this called what it is

almost all the time i feel that it is unfair to get generalised and/or categorised because of sex. sometimes it just doesn't work that way. women feel like 'men' and men feel like'women', and there should be no excuses for such behaviour, no one should be questioned for such seemingly unlikely behaviour. all those of us, who sometime dont fit in with the world's classification of us, let's not change ourselves, let's change the world.
