Fat people are bad, but that doesn’t make smokers good. Bad smokers, bad fat people.
It’s not jealousy, it’s impinging on others’ rights that creates the anger. When I’m walking down a street and the guy in front of me is smoking (causing me to breathe in his smoke), I’m angry. When I’m on an airplane or bus and a fat guy sits down next to me, I’m angry that his bulbous thighs are resting on my lap.
The amount that your badness affects me is directly proportional to the anger it causes.
