I agree with you. I don't go out of my way to hurt big people and I don't outwardly do so on ourpose. I just have to catch my initial bias and push it aside first, which I'm working on, I know it's a me thing, for sure.
I agree "happy at any size" can be an acceptable attitude, for sure, but I disagree with "healthy at any size". Obesity puts stress on organs and body parts, simply just because of the extra weight, even if everything else is fine.
