Mitt Romney’s comment about cutting funding for PBS at the first Presidential debate has made Big Bird one of the most popular costumes for Halloween this year.  But that’s not all good news.  The Children’s Television Workshop, producers of “Sesame Street,” sent a cease-and-desist letter to the company behind a “sexy big bird” costume.  It’s not just a matter of licensing revenues and copyright protection.  The characters who are important to children should not be trashed by being sexualized.
