TLDR: Being fat is very very unhealthy, and all the culture around fat acceptance is a disgrace and an insult to our intelligence.

There is a fine line between being opposed to fat acceptance and thinking performative cruelty works.

(It's does not. It made me so much worse. I have nothing but bad things to say about the medical "professional" who catastrophized my diagnosis to "wake me up" and then shrugged when my response was depressed resignation.)

You can't depend on people being nice to take care of your own health.
