It's the sad mentality of "fat culture"- they grow up seeing others that have fucked up their bodies/lives and thus assume it to be "acceptable".  They see nothing wrong with allowing themselves to reach weights of 300lbs because "there are lots of people like that! I'm okay with my fat! Love my morbid adipose anyway reeeeeeeeeeeee". They're a scourge, spreading lies of acceptance and false perceptions of whatever they think health is, infecting the next generation with the idea that it's totally fine to be lazy (because anything remotely challenging is hard) and that it's perfectly acceptable to smother your feelings with cheesecake and soda until you're so addicted to sugar you made yourself diabetic it's the government's problem. The new American dream, everyone.
