Why does Cartman hates everything and everyone?

Cartman: Isn't it obivous? It's because everyone here are assholes. And so I'm an asshole back.

Amber: Yeah, sure. Actually I think I know why. I think it's because of Liane or as you know her as Mrs. Cartman. Everyone knows how she just lets him do whatever he wants...which is terrible. And since Fatass is such a spoiled brat he thinks it's okay to be an asshole when someone disagrees with him.

Cartman: Don't bring my mom into this.

Amber: I'll stop it when she stops brining men into her bedroom.

Cartman: Fuck you guys!

Amber:....Thanks for reading. Bye Bye Fwends.
