I found this (old) website with a huge list of vividly described propaganda and debating techniques and think it's worth sharing. It's not by pure chance that some of the propaganda techniques are illustrated with examples from tyrants and warmongers.
(The author seemed to have a bigger feud with a certain organisation, though.)
P.S.: Google / Blogger is forcing the stupid new interface on us bloggers now. Be patient if strange things happen, especially concerning format, disappearing posts etc..
