What about on TV? How many fat actors or actresses get gigs that play the good guys? How many fat people do you see on regular TV shows that aren't being berated or made fun of?
And here I am looking at the commercials for American Idol (I swear I am watching Criminal Minds!) and what do I see? No one that looks like me, even in the audience. Then a judge says "you look like a million bucks!" to some contestant and it reminds me of the awe and surprise that this woman received because she wasn't conventionally pretty. Seriously, look at those people's faces before she sings and then directly afterwards, like it was a surprise or something that she could actually sing in a fucking singing contest.
Anyway, thin privilege is being able to walk into any store and see models that look like you (let alone clothes that will fit you, clothes that will be cheap, and employees who don't look at you or speak to you in disgust). It is seeing movie stars and politicians (especially the women) and lawyers and CEOs and managers and doctors and biologists and especially those who run studies and teachers and anyone else in power who look like you that you can aspire to.
Thin privilege is having role models that look just like you.
