The type of "Liberal," who tears down other people's signs, to prevent anyone hearing their message, should always be placed in quotation marks or italics, or spelled or highlighted in some manner that distinguishes him from a real Liberal--the 19th Century type, where the word still had some meaning other than totalitarian egalitarian.
