Two problems, I think: 1) is that these fats are narcissistic morons. They don't see any flaws within themselves. Since they think the sun shines out their asses, it doesn't even occur to them that other people don't see them as these amazing, perfect mates they believe themselves to be 2) is that they don't see bother people as people - they see them as objects. People have emotions, preferences, desires... objects don't. Objects are there for you to use as you will. (You don't ask your hair brush if it wants to brush your hair, you just use it.) This is how fatties see other people.
