I have had read postings and posted over several years, and I monitor several Civil War Message Boards frequently. I have seen very few "hate messages" posted by those that post regularly and have knowledge about the Civil War. The vast majority of postings are by those whose only purpose is to exchange or to share information and links to news articles that affect our heritage.
To describe some of the posters as "Idiots" does a disservice to those who are truly the certified idiots iof the world.
