Feminist love throwing around privilege, yet they are the most privileged class in modern history in the West

Your entire thesis is a solipsistic mess.

I will now extend you the courtesy of explaining how, and why you are wrong.

First off, you missed the entire premise of my post. Nowhere did I advocate for obesity, nor hold it up as the bastion of truth, or the way forward for society. I merely pointed out the inconsistency of his argument and contested the idea that obesity = power in contemporary society. You invented the rest.

Now to the specifics:

"Obesity is horrible and should never be praised in any intelligent and moral culture. It is, in fact, excess and gluttony just as OP said. An obese person visibly demonstrates their lack of self-control over their diet and overall health. Obesity is not a fashion choice or something that you are just "born with". It is a conscious decision to harm your body just as someone would do with opioids or other hard drugs. It is completely natural and perfectly rational to think that obesity is an abominable aberation of the human form that is a result of excessive self abuse."

Oh, it's horrible, is it? Well putting aside the utterly useless subjectivity of such a pointless, loaded term, let's consider the idea that obesity is chiefly a result of excess or gluttony. How do you reconcile that idea with the fact that it is often cheaper to buy a Happy Meal at McDonalds than it is to go buy fresh produce and meat from a supermarket? How do you reconcile that idea with changing economic conditions, such as the casualisation of the work force, job insecurity, and all the other market factors involved, people have less money to spend on luxuries like gym memberships, let alone the bare essentials? It's all well and good to espouse the virtues of healthy eating (a virtue I would agree with, by the way) but it's very hard to be philosophically pure when you can't make rent and the kids are screaming because they are going to bed hungry. To me you sound sheltered and naive. Have you ever had to want for anything? Have you ever had to choose between paying rent, or having the power cut off? Plenty of people face that choice every day. And in that situation, paying for the food that you can afford is the rational choice. This may shock you, but starving to death generally results in poor health outcomes.

"Additionally, there's a reason it's associated with low class today. It's because we live in a wealthy country and not some tribal land that can't even afford roads or plumbing in their infrastructure."

This is just baffling and betrays your ignorance of history. Henry the 8th wasn't from some "tribal land", he was from this little nation called England. Maybe you've heard of it, it was one of the most powerful nation states in the world at the time of his coronation. What about Kublai Kahn, you heard of him? In case you haven't, he was the leader of the largest contiguous land empire in history. Do you think his problem was a lack of resources? Not sure if you've ever seen any paintings of him but he would certainly be considered obese by contemporary standards. How do you reconcile that? He was more alpha than you could ever hope to be. Uh oh, looks like you might be full of shit.

The point that went sailing over the hollow wasteland known as your skull is that it is in fact the elites of a society that set the trends or standards for the rest of that society. How many obese celebrities do you see? Well apart from some notable exceptions like Rebel Wilson and the like, the vast majority are slim, well toned, and so forth. And what resources do they have at their disposal in order to achieve this goal? Only the best personal trainers, dietitians and other support staff, not to mention they can afford to buy the right food and have someone cook it for them. To make it clear, I am not suggesting this is outside the reach of the 'average' person -- clearly it is not -- but that there is a reason for why obesity is no longer considered a characteristic of the rich and powerful. This is what I was talking about, from the very start. Not that obesity is something to be admired or pursued, but that the suggestion that obese feminists are somehow attempting to derive power or status from their girth is absurd.

"Get your head out of your spoiled first world mindset and be grateful for what you have. In many other countries, they marvel at our lavish lifestyles and how we can actually afford to be fat gluttons. But we know that it is lack of good character, and not only wealth, that makes people actually become fat gluttons. Bad character is associated with low class."

Thanks for the suggestion, allow me to respond in kind by inviting you to remove your head from your arse. "Bad character is associated with low class." Really? What the fuck is "bad character"? What is good and bad? Do you really think that way, in such blind absolutes? Holy shit, I feel like I'm responding to a kid in primary school, at least developmentally -- and maybe I am -- but seriously, what the fuck do you even mean? Do you arrogantly believe you are the arbiter of right and wrong, of good and bad? Who voted you into this position? Did you have to sign some sort of contract? The very concepts of good and bad are such blunt instruments for what is a much more complicated situation. Do you honestly believe that the entirety of human endeavour and expression can be reduced to these binary states? For your sake, I truly hope not. Get the fuck out of here with this moralistic, pearl clutching bullshit. Open your bloody mind to the possibility that life is not quite so simple as morals found in the fairy tales your mother told you as a child. And no, before you even try, I am not arguing for relativism or any such nonsense, but you came in here thinking you were dropping truth bombs, but what you delivered was the musings of a naive school boy, delivering his first oral presentation of Why The Germans Were Really Bad In World War 2, Man. You're embarrassing yourself. Read a fucking book.

Better yet, read the goddamned sidebar.
