I criticize neither and I don't think it's okay but in Sweden at least it's okay to criticize both, more obesity than smoker these days. I'm overweight, people are appalling sometimes. Actually most of the time, I don't ride the bus any more because of it. People will outright laugh at you, I'm not kidding. Some will just stare and snicker at you and others will taunt you openly. If you even defend yourself you will be attacked by others around you verbally.
I'm not overweight because I have an eating disorder, I eat normally but I was depressed for many many years because of the situation I was in with my school where my teachers and class mates bullied me. I basically stopped going out or moving at all on a daily basis and gained a lot of weight because of it. It's not all about eating disorders or eating a lot of candy, tbh some of the stuff that media outlets claim people like me drink and eat constantly like some sort of eating machine I can't afford. It's very common that obese people are paraded in the media as some sort of freak show and that it's as easy as taking two steps to loose 100 pounds in weight. It isn't, a lot of health issues that people don't talk about is the constant pain. Cracked feet that bleed out, busted knees and sometimes your feet can twist causing you even more pain.
I'm happy with myself the way I am, I at one point cared what others thought and said but I don't any more. I am losing weight though but I came out of my depression, it is a very slow process though. I really do not like it when others bully or criticize others for being overweight. The fact is you don't know why, it's not okay to go at others for smoking either. You just don't know why they do the things they do, everyone has a habit they should probably quit. Why is yours any different from anyone elses? I knew a woman who weighed more than 300 pounds, want to know why? She wanted to be unattractive so that her father wouldn't rape her any more. Her father used to take her down to the basement when she was young and rape her over and over again but he stopped doing it when she was overweight because he was no longer attracted to her. So she kept eating and eating. So she got an eating disorder because of it, she felt safe from him because she was overweight. Don't criticise others until you know why or how, it's not all black and white. The world is far from 2 dimensional, being overweight doesn't always concern food or the overconsumption of it. Why someone might have an eating disorder isn't always that simple or why someone is smoking. It isn't as simple as just quitting. When it comes to eating disorders, psychological trauma is more often the case of why and how.
