You are spreading false information. Look it up! Private citizens making libelous statements can most definitely be sued. Public officials and figures have a harder time proving defamation, but it has been successfully been done in the past. Lying about someone on a public forum such as Free Republic most definitely can open you up to some form of legal action in the future.
