The Nizkor Project has a special feature on their site: the complete text of Labossiere’s Fallacy Tutorial, which outlines 42 forms of errors in logical judgement. A good read, if only to improve your critical thinking. What I found particularily interesting is how politicians and public relations folk use many of these fallacies to boister their agendas.
Unfortunately, the Nizkor Project has probably seen quite a few fallacies in its day. Its site has been up since the birth of the web. Nizkor’s handlers are grizzled veterans in Internet flamewars, as the Nizkor Project is dedicated to refute Holocaust deniers and their claims with logical arguments and insurmountable truths.
