I'm saying once you reach a certain point, it IS your fault. Once my smoking got so bad I was going through two asthma inhalers per week, it was MY fault and I HAD to do something. Same with my weight. Yeah, I have a thyroid problem, I'll always be fat, but once I left the Jack Black zone and started stepping on Kyle Gass territory, I knew I HAD to something.
And yes, there are ways to turn things around. Granted, absurdly obese persons will never be slim, but they can, if they still have some kind of will to live left, go back to being... You know, fat; just fat. Like, normal fat. Like, can actually walk a couple of miles without dying fat.
And, again, people who have the metabolism to eat like that and still be slim and abuse it are killing themselves too, and they are being just as irresponsible if they don't change their eating habits.
What you seem to be suggesting is to just let them do whatever they want to do, which will inevitably lead them to an early grave. That's a valid option, sure, as long as that person UNDERSTANDS that what he/she is doing is basically suicide in slow motion. If they understand that and they choose to take that road, fine, I guess. If they don't understand how much they are hurting themselves, the least society (or their families, if you want to take the "libertarian" approach) should do is explain it to them.
Uh, exactly. In all likelihood, someone who is obese will always be obese. Meaning that the 300 pound person you're ridiculing for being lazy and lacking self control could be down from 500 pounds. Now, if you've just worked your ass off losing 200 pounds, what the **** good does it do you to have someone skinny walk up to you and give you shit for being fatter than them? The obvious response would be "go **** yourself. I've just lost 200 pounds, how fucking much have you lost recently?"
Hell, you ought to know this since you're admittedly always gonna be fat. You might have a valid medical excuse, but I'm not gonna know that if I walk into a store and see you standing there looking all fat. How do YOU like it when people see you, see how fat you are, and then treat you as a grotesque lazy glutton who just can't stop stuffing his face?
