The obvious parallel is, both the public library and public parks (or wherever these statues were), are financed by the state/city. If the rationale is to remove offensive from public view then where is the line drawn? Aside, I honestly had no idea that the Constitution protects books. What other mediums are protected? Paintings? Obviously statues do not enjoy such protection. Sincere question; if enough NA's got together could they force the covering of Mt. Rushmore with a giant curtain, for example?
