Why is it still accepted to discriminate against obese people?

Why is it unacceptable to say derogatory things about different ethnicities, or colours, but it's ok to be mean to fat people? People are outright nasty to fat people, and I don't think it's right. I just saw a program where a woman wore a fat suit, and tried to get people to stop for a survey, they ignored her, and even laughed at her. When she was back to normal, they were more than happy to oblige. Why are people so nasty to fat people?
