Simply a reply to the OP (as I dont have the time to read the whole thread yet):
Oh fuckin can it. Give me one good reason why people shouldn't be comfortable in their bodies? Name one. Name fuckin one. Even if you bring up how much of a health concern it is, it still makes you prejudice because their health is none of your concern. I for one love the curvier and larger women. I mean, they're still people too, ya know. I mean, sure, I have a bit of a gut, but I also enjoy eating "like a fat kid" as I often put it to my friends, just simply because it amuses me. At the end of the day, people who are proud to be fat are more comfortable int heir skin than you are.
There's a big (ha) difference between being comfortable in your own body, and being on state benefits and registered disabled because you don't have the intelligence or willpower to put down the fuckin' pie. I love the fact you've got your balls in a knot over me being judgmental, and then in the same paragraph judge me for my thoughts. It's great. Put simply, compare someone who is fat because they eat too much, to someone who is thin because they don't eat. At their core, neither one is a medical issue in itself. Being underweight is unhealthy, being overweight is unhealthy. But there's this stigma where giving advice regarding body size is completely hated, and I don't understand the reason why. If you eat Burger King 7 days a week and supplement it with TV dinners and cheap ready-meals, unless you do a lot of exercise you're going to be fat. If you do all this and don't exercise, the person at fault for the health problems arising from your weight is you. And yet people think it's acceptable to encourage that behaviour because "fuck the haters"? How about fuck the enablers instead.
Affray hit it on the head. There's a difference between being overweight because of prior medical conditions, and being overweight because you're a lazy shit with an appetite for McDonalds. However, even with other medical conditions there are things you can do to lessen the amount of weight you put on. Have a bad example because I feel lazy.
I suffer from regional enteritis, or Crohn's disease. It gives me the opposite problem; I struggle to put on weight. I am underweight still, but I used to be a lot worse. Despite my medical condition, I make myself put on weight because it's healthier than the alternative. Now flip that to someone who has a medical issue that makes it hard to lose weight. Should they try to lose weight in order to be healthy and give themselves a better chance at life, or should they just grow fat because they're "beautiful as they are"?
The problem that a lot of people miss when dealing with this, is they believe it is all about appearance. Being happy or unhappy with the way you look, being happy or unhappy with the way other people perceive you, wanting to look a certain way for certain people, etc etc etc. It's not. Appearance is an aspect of it, but the core issue is the amount of health problems that stem from being fat. And in addition to that, the extra money spent looking after these people if and when they reach a point where they can no longer climb the stairs, or get out of bed, or walk, or shower without help. If they need to be taken to hospital they need special equipment to be brought in order to get them into the ambulance, hoists, super-strengthened wheelchairs, strengthened stretchers. When they get to hospital they need more people to lift them into bed, they need a reinforced bed, etc. EVERYTHING gets supersized, and their weight poses a direct problem for any medical professional involved.
I often see people berating drug-users, claiming that the medical profession shouldn't waste money helping them because they bring their problems upon themselves. Honestly, I agree. However, I feel the same about the clinically obese.
And, Sushi is right too. Tumblr is a fucking cesspit for things like this. White Knights all over the place, even when they're trying to defend something absolutely moronic.
