Goebbels was not original. He was honest about that - he gave credit to the British Propaganda during WWI for showing an unprepared Germany what could be achieved with completely ruthless and dishonest propaganda. He tried to copy it, but German propaganda was clumsy, and never managed to enter the mindset of those it was aimed at.
These days political propagandists use scientific methods derived from business marketing and the advertising industry. It is all much more sophisticated.
I don't know if I'd say that Limbaugh is a propagandist because he is speaking to a willing audience. The people that are bad are the people that engage in the manipulation of people that don't know they are being sold a message.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
