Think about how pity is different from hate. When you pity someone, it is like you are looking down on them. There is no way that you could pity someone that you think is just as good as you. We do stuff like pitying a sports team that is way worse than the one from our school. Or we pity some country like Haiti.
But when you hate, you are putting the other person on your own level. You don't hate someone who's below you -- you either ignore them or you pity them or something like that.
So Pony doesn't want anyone looking down on him. He wants to be seen as an equal.
