 :::As for your comments, no, 'common knowledge' is not acceptable. The article has far too much unsourced material already (I am currently trying to rectify that, without a great deal of success), and adding more isn't going to improve things. Particularly when your supposed 'common knowledge' seems to consist of a cobbled-together collection of disparate subjects. As far as I'm aware, Native American Reservations have never been referred to as 'no-go areas', and neither have leper colonies. And as for France, if there is material on this, cite it. There is no way whatsoever that we are going to include material on such a sensitive subject without proper sourcing. Though frankly, given the problems I'm having trying to find sources for what we have already, I may well propose the article for deletion - Wikipedia is not a dictionary, and unless a single source can be found to draw the existing content together, it may have to be deleted as synthesis.
