There is a difference between being over weight and being FAT. That is NO reason why others who do not take up two seats should have to suffer because of the fat persons inability to either control their eating or excercise. And please don't give me any genetic or medical reasons stuff.
The government studies also say that it is because of overeating and lack of basic excercise that the huge-est (intended) majority of those fat people are fat. That is not my problem, nor anyone elses except the fat peoples problem.
If they want to eat like that and not maintain the body God gave them then they SHOULD pay for it, not the others who at least maintain themselves to some degree. Studies also show that a majority of Americans ma$turbate but I don't want them doing that partially on my seat on the plane either.
