Because overweight people are not “less than” average weight people and everyone needs to accept themselves and not berate themselves for their shortcomings. Just like smoking or anything else, easier said than done to get a handle on for many. I think we all learned in or should have anyway, in Kindergarten, that people come in all shapes and sizes and colors and everyone deserves to treated with kindness and respect.
Some people are just more prone to putting on extra weight, whether that is due to poor habits, a desk job or genetics. They struggle and have a harder time maintaining a healthy weight.
Fat people wear their weaknesses on their bodies for the whole world to judge but closet alcoholics, drug abusers, shop-a-holics can conceal their weaknesses from public criticism but all of those personal issues are just as “bad” as being overweight. Humans have their challenges and weaknesses, what else is new? I have to work really hard at my weight, I love to eat, I love to cook and have gone up and down a few times in my life. Never morbidly obese but 30–40 lbs. or so.
To maintain a perfect weight means I am, literally, starving all the time and have to walk/run 3 miles day. Fuck that, not gonna happen anymore, did that for 35 years and if I’m a little chubby in my older middle age I don’t care, life is short eat the fucking cheesecake and drink the wine. Ya gotta die of something, I say leave people alone ad judge them on the size of their heart not the size of their ass.
