Conservative religious people like boycotting, especially in the U.S. I remember how in the 1980's they were boycotting Proctor and Gamble products. Why, you ask? Because the original logo for P&G looked Satanic to them. Turns out that the 13 stars are not about Satan but are for the original 13 American states, and that the face is "the man in the moon." See http://en.wikipedia.org/wiki/Procter_%26_Gamble (logo controversy section) for the whole story if you are interested.
In more recent years, the religious right have boycotted various products and companies, including Disney because Disney was having some special days for gay and lesbian people. This cartoon was inspired by such things.
