Sure, the author may have meant it to be funny. I don't think Ellen or Kendall have it in for anyone by sharing the site. But the author comes across as spiteful, and it just really isn't funny. Substitute any other cultural/ethnic group for South, and see what you come up with.

He also obviously hasn't traveled around much. As someone else so aptly pointed out, no part of the country has a corner on assholes.
