Both DD's - Stupid is abstract, you can't see it. It's a matter of opinion and one person's stupid is another person's brilliant (ie GW Bush). I think fat people have enough problems in this world without the rest of us trying to make them feel worse about themselves. It's like making fun of a smoker with lung cancer.
DrewD - If one of your adorable daughters came home bragging how they teased the fat kid in their class would you give them some good lines for future use? I don't think so. I doubt you want to teach your children to be mean and to act like bullies. You know that kind of behavior will eventually backfire on them.
DD22 - What I said to you stands. You need to practice being nice not mean. Don't fuel your own raging fire.
