Fat people....question for ya.

vivid2012

I just had a guy on the radio say that he doesn't mind being called fat by other fat people
like this one; http://tinyurl.com/3rokwur
but if a normal sized or skinny guy/lady
like this; http://tinyurl.com/3gtlgxe
says it, it pisses him off.

Is this normal, or is the guy just being a *****? If yes, does that make you a fatist?
