3) I notice a lot of people seem to think it's okay to treat people badly if they have no use to you or are inferior. They have the attitude that people who are inferior (or not doing as well as they should) should feel bad.
I think this is correct.
My mother likes boys more than girls, she thinks girls are inferior.
I have four older brothers, I'm the only girl.
When I was at a party when I was ten, the mother of the girl who had her birthday, said to all the girls: I like you all, except Run. The party went on. I never understood why she said this, and how it was possible that she thought to get away with a remark like that. Unfortunately, my mother was not somebody who stood up for me.
Nowadays, I think that my mother had told the mother of this girl, that she liked her boys but that her girl - me - not have had to be born, or something like that. That is the only explanation why the mother of that girl thought she could get away with it.
The mother of that girl and my mother are still friends.
I think of a way to let to know that mother of that girl, forty years later, that she can burn in hell.
