Is it normal that i think of "body positivity" in a different way?

I've seen many body positivity posts and advocacy and awareness, but when I usually see these posts, they only about skinny and/or plus sized people. Chubbier and more plus sized people and skinnier and more slender people are alright but I obviously don't advocate being too unhealthily skinny to the point of Anorexia and being obese or being fat enough to where it affects your daily life.

I feel like body positivity should belongs more to amputees, victims of vitriolage, survivors of cancer who have had body parts removed, people born of deformities, people of skin conditions, car crash survivors, etc... you get my drift.
