Some people would claim that wrongful discrimination is treating somebody differently because they are a member of an identifiable group – a woman, for example, or a black person. That is a sensitive definition but not a useful one. I spent more time in my 20s pursuing girlfriends than boyfriends, and I must admit that this bias was everything to do with the fact that the girls were all members of an identifiable group.
