Body positivity is not about categorizing bodies (especially fat ones) as good or bad.
And it's not about waiting around for fat people to wake up, realize they're fat, and decide to do something about it; it's not about asking people to change. (Though if they do decide of their own volition to make changes to their bodies, that's their own business.)
It's about loving your own body and accepting other peoples' bodies exactly as they are right now, regardless of whether or not they ever change.
"At some point I was like, you know, it's fairly likely that I'm going to be fat forever, so why am I putting off figuring out how to live with that?" West said. "Why not try to figure out how to be happy now?"
