Apparently, thin privilege is getting the "you're probably that thin because you don't eat meat", "you don't want cake? you're gonna be one of those girls that diets, aren't you!?" and "you should eat more" lectures every other day. It's also hearing your best friend ask "don't you hate it when guys like girls like thigh gaps?" even when they know you have one. It's also your boyfriend telling you how thin you are every time food is brought up. How can people say we don't have problems???
Oh, they admit thin people have problems but "being told to eat a burger once isn't a big deal" and you can "always get it tailored or shop in the kids section."
their whole argument seems to come down to "yeah, but we don't perceive your problems as bad enough to count. also ours look worse when we deny all of yours."
I mean, maybe less people would say "but thin people DO deal with that, lots..." if they quit saying "fat people have to deal with this BUT THIN PEOPLE DON'T NOT EVER AND NOT SERIOUSLY"
