I propose that we stop calling energy-killing, car-addicted, city-uglification
and start branding this destruction
Use anturban to describe the intentional voids left where place and nature once existed and use suburban to neutrally describe settlements that exist on the fringes of major urban centers.
While modern suburbs may be mostly anturban in layout (because they've been built during the last 60 years, anturbanism's Pyritean Age), they don't have to be, or remain, that way.
And many urban areas far from the suburbs have devolved into the anturban during the same 60 years (see the horrendous east side of Memphis' Medical Center).
It's better if we can insult dysfunction without insulting our fellow citizens.
