Thin privilege is being able to follow your passions and indulge in your obsessions, regardless of what they are.
There is a fairly popular video going around, which is a lovely documentary about a place called Sky Ice in New York. The owner and creator is obsessive about designing new ice creams, and it is beautiful and inspiring. But the whole time, watching it, all I can think is that I’ve always wanted to have my own ice cream shop too, but I can’t because I’m fat. You can only be passionate about food if you’re thin. If you’re fat, you’re not passionate, you’re a disgusting pig. She is only allowed to say that she eats ice cream for every meal because she’s thin.
