I only want to lose weight because I hate fat people
Thats harsh. Do you hate all fat people?
I only hate the obese ones, I don't know why humans feel they need to consume so much food
Judging people by their weight is an awful thing to do. You don't know the circumstances behind their weight issue or if they have a mental or physical inability to lose weight. Be kind to people and don't force your own feelings on others.
I don't care, I could always leave all my fat friends.
How would you feel if people discriminated against you? Having hate for people regardless of disability is wrong.
