Have you noticed that obese, unattractive women are often quite hostile and angry? These women are mistreated at a far higher rate than others, and become jaded and angry and expect each encounter to be a fight.
This is probably an unpopular opinion, but I think I would far rather be any type of minority (black, native american, arab, Muslim, female) then to be ugly or fat even if I was a white male. I think there is a far stronger bias against fat people or unattractive people than there is against other groups.
