I don't think anyone meant any offense. The topic is about making Sims of different body types, it's kinda hard to not come across as rude. But it's a game, is it necessary to be PC about game characters?
I always make my Sims thin or in the middle, I don't like the way they look fatter. But that doesn't mean I have anything against people who are considered "overweight". I am overweight myself and wouldn't consider myself the paragon of beauty. I just like my Sims to have a certain look.
