I'm willing to concede there is a genetic component. But I believe you are exagerrating it's effects. Metabolic rates certainly differ; but that would only effect the time it takes to burn calories. It may take someone with a slow metabolic rate longer to shed fatty tissue, but it's not going to prevent someone on a caloric defecit from losing that tissue.

Do they have to become "skinny" (which isn't a much healthier state)? No. But then neither should they be complaining about it. I'm not going to respect and accept someone when they complain about something they want changed, and do nothing to see that change happen. Do all obese people do this? No. But I suspect the majority do, just like many non obese people.

Being obese is not akin to being black, white, gay, straight, Canadian, or mentally retarded. Your colour, nationality (largely), and sexuality are not the result of your choices. Obesity (in almost every case) is.
