Facebook: "Likes" Are Protected First Amendment Speech

Facebook has filed an amicus curiae brief in the appeal of a sheriff's deputy who was fired after "liking" the campaign page of the sheriff's election challenger.  The brief argues that a "like" on the social networking site is a kind of speech protected by the First Amendment to the U.S. Constitution, and requests that the appeals court overturn the district court's decision in the case.  The district court ruled that a like did not merit constitutional protection since it did not involve an actual statement.
