I think his point is....they are CRIMINAL ALIENS.....(The mere fact they are HERE is a crime!)  ANY country has crime, but how much LESS crime would we have IF criminal aliens were deported?  Aliens as "from another country".  
Nice try at a strawman argument, but the fact is, 11 million (I believe a very LOW estimate) criminal aliens being tossed out of the country would be a good thing...for national security, for crime rates, for lessening the impact on our education, healthcare, and other systems.   And if  "dreamers" have a problem with their status, I suggest referring them to their parents, who are responsible for them breaking the laws of our nation in the first place.  And with any luck, and a SCOTUS acting in accordance with the Constitution and a proper reading thereof, those born here of criminal aliens would also get the boot.  Children of diplomats born here aren't citizens, and THEIR parents are here LEGALLY!
