"The U.S.-Mexican border es una herida abierta"

This key paragraph describes the border as a place "where the Third World grates against the first and bleeds."  Anzaldúa uses graphic imagery to convey the unhealing ugliness that is created by the border.  This video by ThirdWorldThirdSpace shows a two-minute drive along a stretch of border wall, accompanied by a reading from Anzaldúa's preface to Borderlands.
