Why liberals don't move to cheap metro areas

Political Cesspool host James Edwards has a post on his website on crackheads in Detroit http://www.thepoliticalcesspool.org/jamesedwards/2011/06/21/crackheads-out-of-control-in-detroit/. Edwards asks why don't liberals move to Detroit? I want to ask why white liberals don't move to Detroit but such other places such as Riverdale, GA,(Atlanta), Atlanta, Prince George's County Maryland (DC), Baltimore City, Braddock, PA (Pittsburgh), or other wonderfully diverse areas. These liberals can embrace the wonderful diverse cultures. They can invite their diverse neighbors for dinner parties and cookouts. They can worship in the same churches, and send their children to the same school. Then after a decade or so living in these gorgeous mosaic's the white liberal children can date, marry, and procreate! They can live here next to nothing!for That will show us! Now; when people like me don't want to live with low class minorities because we value clean streets, safe streets, home upkeep, peace and quiet, and  want our children to attend public schools to receive a decent education and not have to worry about our children being physically or sexually attacked we are called racist! But when a liberal is asked why they live in the suburbs, the cite schools. Liberals will not live or send their kids to ghetto schools because deep down they know the truth. Yet these same assholes have a "coexist" bumper sticker on the back of the car!
