The problem is that in the USA the obesity rate has gone through the roof and when people come forward saying that fat acceptance is good and you shouldn't try to lose weight, it's unhealthy for the whole nation. As I said, because people search for excuses not to do something, not to work out, they will find relieve in this fat acceptance movement.
It's a complicated matter, people should accept their situation (not talking only about body weight), and if they consider it shitty, they should change it, nevertheless try to promote it as something good because they are insecure.
I think what's missing here is nuance of the situation. Lets take a woman who is 5'9" and 175 pounds. BMI says she's overweight, she does have some extra fat on her, but all her vitals are good and is overall healthy. She should be able to so say, you know what, I like my body, some people might say I'm fat but fuck them.
Now if she were 275 pounds it becomes a different question. No one is really healthy at that BMI. It's really only a very small subset of people who are pushing this condition to be normalized and they should be ignored like most fringe groups.
I see this a lot, conflating a fringe part of a group with the views of the larger group. All BLM is about is an excuse to riot! All conservatives are neo-Nazis! All Muslims are terrorists!There's idiots in every group, don't let them detract from the larger message.
I mean there's a huge difference between "out of shape" and "medically unhealthy". I'm not saying being overweight is good for you, and it can definitely lead to medically unhealthy conditions (heart disease, hyper tension, diabetes, etc), but grouping all people that are out of shape into the same group is simplifying things and vilifying people in unproductive ways.
Let's take Donald Trump for example. He's in shit condition, but he's medically as healthy as anyone his age could hope to be. He looks like a slob, but his organs are chugging along just fine. Someone could be in perfect shape and still have underlying problems that are a bigger danger than working out can do anything about.
Some people just don't care about their weight. I'm fine with them living how they want to live. The people that suck are the ones that complain about it all the time but do nothing about it. Also a general societal encouragement of not being healthy sucks.
I read a reddit comment that poked some pretty solid fun at it: "KMart is changing their plus sized items to 'fabulous sized'. Hospitals are also now changing the name of Type 2 Diabetes to 'Fabulous Diabetes'.
