Many people consider laughing at jokes that are at the expense of ethnic groups to be an expression of bigotry. I certainly do. For people who hold this view of ethnic jokes, to be compared to someone who laughs at them is to be called a bigot. That's definitely the meaning I got from that story. The woman in the story is a bigot who laughs at jokes that are told at the expense of other ethnic groups. It is a huge assumption to say that most of the people posting in this thread are so bigoted that they laugh at jokes that are at the expense of other ethnic groups.
