It is like the old routine on the old Dick Cavitt show. He invites a representative of a Polish citizen's group to protest Polish jokes. The representative tells insulting joke after joke and the audience cracks up.
The only difference here is that WND doesn't realize that they are part of the joke. It makes it difficult to ever take them seriously.
I understand humor, I also know dirt when I see it.
Why hit a mule with a hammer when a nice, soft two by four will do?
