It's about mental retardation being a real disability. The disability is hard for the people, who have it and the people who love them. I know that makes no sense, but we don't make fun of many disabilities.
Retardation is a serious disability that some people and families have to deal with.
I do not like your use of the word. It offends and hurts me. I agree that the writers aren't up to par, but expressing this as retarded is not right. Thank you for saying. Thank you for saying that.
