While there are so many books and papers on the concept of "whiteness," I have trouble finding scholars who wrote specifically on whiteness (its preservation or destabilization) and (urban) space. How does (urban) space contribute (or not) to the preservation of whiteness and white privilege? To what extent has the protection/defense of white space contributed to the formation of the American character (I'm thinking about rural farmers and vigilante groups protecting their land against menacing, often radicalized "others" in the Republic's early years). I have already read Cheryl Harris's excellent essay Whiteness as Property. I now need to read a book/paper that addresses specifically whiteness and space (private property, land, urban space if possible).
