Duplicate content means "it's been found elsewhere on the Internet" and that applies whether you are the original writer or not. The FAQ is quite clear about duplicate content. hubpages.com/faq/#duplicate_content.
It is important to remember the Duplicate Content within a hub is not against the TOS here at HubPages, but they do indicate that you cannot link out to any other website if your content is determined to be a duplicate. In the grand scheme of things, there is very little you can do, as even HubPages asks that you do not contact with information about how your article is original.
It's just like print publishing, you can sell your articles to as many publishers who will buy them; however, each one really needs to be rejigged:1) to suit the readership of the new mag.2) so that you can sell for first serial rights again, and again. When you put the same stuff on different sites, you're annoying the editors in the same way you would be annoying print editors if you sent the same article to all of them.
Just re write each article even though you are the original author.
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.
