Bear with me...
I think that a lot of the problems have to do with fear of distorted images. I recommend mistaspakkaman's excellent description and analysis here as a starting point.

We may not have a genuine fear of fat people (or black people, or midgets, or whatever group you care to point to) in terms of them making us want to run and hide, but I suspect that all of us have a touch of this which causes us to be uncomfortable around people who don't resemble us.

In the case of the Lard Family, it's compounded by the issues discussed in this thread.

Discuss.
