underweight is worse than overweight. Because you can only be so underweight before you die.
This meme is incorrect tho. Both things exist on both sides. Sometimes its fair, sometimes its unfair. My cousin is underweight and he can eat what he wants, he wont gain anything. Meanwhile some people think of sugar and they will get fatter.
The delusion of fatties that skinnies are loved is quite fantastic. How much do you think it's enjoyable to be stopped on a street by a complete stranger and told one of those things in the picture?
The only difference is that if someone is making fun of a fat person, they at least know they're an ass, while bullying a skinny person is actually encouraged as helpful, because we need to be told to eat and stuff.
Plus you can always find someone who finds a fat person comfortable as a pillow, while around skinnies people just bitch that the bones hurt them or similar shit.
