Your argument,
Johnny Vodka seems to be all based on the oh so wonderful neo liberal mantra of choice. We're all rational humans making rational choices and if you're fat you're irrational (how can you do something to damage your health so badly and be rational?) that's the basis of your argument. It's not completely incorrect, choice, personal action, responsibility and so on comes into it but when is it ever as simple as that? Your argument is exactly identical to that used by tobacco companies. It's one they used repeatedly to get themselves off the hook. 'People choose to smoke we just provide the option' except they weren't. They knew precisely what they were doing, that nicotine was highly addictive, that smoking caused cancer etc. They knew that smoking wasn't natural, that it provides no benefits whatsoever to health, mental and physical, so they had to carry out an enormous, incomprehensibly enormous when you actually look at it, to get people to take up smoking because half their customers are killed by their product. Smokers choose to try their first cigarettes of course but do they then consciously make a rational choice to need to carry cigarettes around all the time? To smoke one every 20 minutes or so? To get to a point where they feel they can't carry out simple tasks like answering the phone without lighting up? To make themselves think they actually enjoy it and on and on? Of course not and it is, in my case at least and I'm sure many others, very similar to how I approach food.
I've probably revealed more about myself up thread than necessary but nevermind I'm not that bothered as it's anonymous so I'll carry on. I have an addictive like approach to junk food. It's the main part of my diet. It's not all junk but it's bulky carbs a lot of the time etc. I feel like I 'need' it, I feel shame when I buy it, I have a certain kind of high when I eat it, but only for a few seconds (like a smoker) I feel shame after I eat it, I don't even notice the taste half the time or particularly enjoy it. I know it's killing me, making me miserable and affecting pretty much evry facet of my life and yet I still carry on, just like the smoker who knows all the health risks but carries on regardless because they irrationally rationalise it (I won't get cancer) and it's the same with junk food. Now, personally I quit smoking despite being hooked from my late teens and for 17 odd years after that. It took me several attempts to quit and even then I can't say for sure I'll be quit forever but so far so good. It's gonna be the same with junk food. I don't like eating it, I don't like being fat but I do eat it and I am fat. That's not rational. Yes of course only I can change it but it's a constant battle, it's one I've fought all my life and it's one I will fight all my life. Yes some people are fat because they like their food but there's probably equally as many, if not more, who are fat because of all kinds of complex reasons (I'm only really scratching the surface with my own experiences I've shared here).
I think, eventually, junk food companies will go the way of tobacco companies because they peddle the shit, it's enormously damaging to health, they market to children and hook them when young (especially true in my case) and they cost the state and the economy millions in terms of health care bills, lost working days etc. They lobby hard to maintain their market control and power, they have armies of lawyers and tons of money to do this and they do all their own 'research' (pay someone to skew results in their favour like tobacco companies do) to counter the science that states how damaging junk food is. If you were looking at this from mars you will conclude that junk food companies and tobacco companies are identical in their behaviour and the harm that they cause.
To finish off. No I don't think obesity is a disability but it certainly can lead to disability through a whole host of illnesses, joint pain (something I suffer from despite being only in my early 30s) etc. I do think there should be laws to prevent discrimination against obese people, in the same way there is against other forms of discrimination (not that they're perfect but they help at least) and yes I feel discriminated against fairly often when, for example, going for a job interview, could be me projecting but that's how I feel. I also think there should be more help with the psychological side of eating as there doesn't seem to be any, not on the NHS anyway. I know how to eat a healthy diet, I know what it consists of and what I need to do to lose weight but there's obviously more to it than that. Only I can change it of course but I just think you should know it's not as simple as you make out. If it was as simple as rationality nobody would smoke, be fat, drink to excess, inject heroin and so on.
