I seriously doubt that 3% of Americans suffer from Festivus. It just seems that way because the disease primarily strikes reporters who can't keep their mouth closed. Festivus is a horrid condition but at least it isn't contagious. Symptoms subside within a few days after the full moon.
I couldn't believe this wackjob, you've got to take a look at the site she linked to! It's a place called the "Lilith Gallery" in Toronto. Here is what they say about the gallery, "In the Lilith Gallery you will find many artworks and ideas of a political and social nature. Some are sexual, religious and/or secular in nature. Some may even offend you."
