Nothing makes me more angry than fat people who try to tell me what to eat for a healthy diet.
I think that sounds a little fatphobic. Do you really mean to judge people's bodies like that?
I can do whatever I want. If you are fat, you are fucking annoying.
Thinking that people are annoying just because of their body size is wrong since body weight has no correlation with one's personality. Instead of making a hasty generalization against people because of their weight, you should try to get to know them before making any judgments. You will make a lot more friends that way and have better social relationships!
