There's a difference between being overweight and being obese.
Being overweight can be a result of hereditary genes, a sickness, or what have you. I don't think someone who is 20 or so pounds overweight should be labeled as terrible.
Obesity, however, that's a different story. There is NO excuse for any human to be over 400 pounds, unless they have some gigantic tumor somewhere in their body. All those gross blobs of failure who ride those scooters even though they aren't disabled at all need to fry. They consume more resources than the average person while not contributing more. In some cases I wouldn't be surprised if they contribute less.
But lets not have a mass genocide of blubber, instead why not use them for compost, or animal food. We should make use of them; not like an 850 pound hambeast is going to do anything worthwhile.
