A good way to fight back against the idea that non-fat people are "normal" and that fat people are abnormal, bad, or wrong is to stop saying it!

For instance, instead of saying something like “I can wear anything a non-fat person can wear” you can say “I can wear ANYTHING!” 

This steers the conversation from saying “I can be like a non-fat person” to “I can be my own person, in this body, doing what I want to do.”

As fat people, we are told that our bodies make us disgusting, and that we should avoid drawing attention to them at all times. When we make statements to say “we can be like this acceptable group!” we are still avoiding drawing attention to ourselves, by putting the other group in front of ourselves. I propose something different.

Make the conversation about you. 

When you say “I can be like that person” as a way of rationalizing your actions, you are vastly limiting yourself. You are setting yourself up to mold yourself around something prescribed as “acceptable.” 

When you say “I can be me,” however, you are giving yourself untold opportunities. You are saying that despite everyone else’s doubt, you are going to become the best you that you can be. Forget acceptable ways of existing - you’re going to choose your own. Forget being like someone else, because this life is your life and you’re done with wasting it. You’re going to be what you want to be, because you deserve at least that.
