Why are fat kids awesome? You can hide behind them and they stop bullets.
I don't think making fun of overweight kids is very polite. Do you think it's funny?
No, I just am saying that some fat kids are good for something.
These jokes have absolutely nothing to do with your sense of humor, and everything to do with the normalization of fat shaming in our culture today. Words matter, and we can use them carefully to express how we feel and then we might actually find ways to understand each other's positions, perhaps even advance our own perspectives.
