having been fat myself, you are right, but your path of attack is not constructive.
Fat people need to get off their ass and stop eating so much junk, got a thyroid problem? take some iodine or get hormones replacement therapy.
depressed? seek help, and do not use being sad as an excuse to eat the wrong foods, healthy food tastes good too.
being fat is not healthy and they do need to make a change, they are ruining themselves, and are such a drain on the nhs system.
*a lot of people are*
