No one is buying that the 33.8% of obese Americans fall into that category - it's a choice for themI buy that many or most or nearly all obese Americans have made lifestyle choices you find repugnant, but I don’t buy that they all do. And for that reason, I do not go around making blanket statements like “It is rude for overweight people to drive up the cost of health care because they refuse to take care of their own bodies.” Some--maybe many--overweight people make choices about their bodies, but some do not.
Furthermore, I know many overweight people who make dietary choices I disagree with but who are also very hard-working in their chosen fields. Your suggestion that overweight people are “lazy and fat” is unsupported. Some are sedentary, some are not.
Overall, I find that your arguments are unsound. But that being said, I don’t think you’re trying to be cogent here, your use of terms like “rude” and “refuse to take care of their own bodies” and “lazy” sets a tone that depicts every obese American as being at odds with you.
To pe perfectly candid, the conversation we are having reminds me strongly of many conversations around discrimination, stereotyping, and bias. Which is unfortunate.
