Carol, thanks for the link and for the support in making my point. The first sentence of the first hit that you see even without clicking on the link is:

The name "Janjaweed" means "armed men on horseback."

Not 'sinister', Carol, that was not in my mind. 'Biased carelessness' was in my mind. There are many more explanations of the word janjaweed in the web or in print using a full translation than the wrong one you have given. I don't believe that everything you have read happened to give the wrong translation. I rather believe that you have read both translations in turn and have kept in memory the one that did fit your bias.
