We're not being oversensitive here. We're also not stupid.
Do any of these people sound familiar?:
- The person who is chummy with everyone in the room but can't look YOU in the eye.
- The person at a store counter who deliberately looks past you to the next customer.
- The person who looks at you up and down first before shooing you away (like when you're applying for a job, maybe?).
Of course, the same happens to people who are of a different skin color, or a different sexual orientation, among other factors. The only difference is that society admits that those prejudices are wrong. So far, Sizeism is barely recognized at all.
It's a battle we're never going to win. The sad part is, it hurts. That person I see every day who can't look me in the eye -- it hurts.
