Ma & Pa's Opinion:
America is a beautiful melting pot. Legal immigration is good.
Illegal immigration is bad and needs to be stopped.
We are concerned that the number of illegal immigrants coming into the country [estimated at 8.7M]
vastly outweighs the number being sent home [reported at 314K] 
Ma's grandmother and grandfather were both legal immigrants, from Mexico and Italy respectfully.
Pa's family has a long history of American roots. His ancestors migrated from Scotland and England long ago.
