Expression and Tigger

The ACLU (American Communists Love Us) has sued a school in Redwood California because officials instituted a dress code which would not allow a child to wear socks with cartoon character Tigger on them. Why do I doubt that the ACLU would care if the dress code banned the Veggie Tales characters? You have the right to express any opinion, unless there is religion involved. This kind of nonsense is what results from the Lemon test, which bans "excessive entanglement" with religion. The problem with this is that "excessive entanglement" is in the eye of the beholder. The Supreme Court would have done better to create no test than it did in further muddying the waters of what is and isn't a violation of church and state separation.
