Hmm, Suzanne. While I appreciate your assumption that I am a blind liberal who relies on catchphrases and terms I do not quite grasp, my use of Xenophobic was deliberate and precise. I was referring to the statement that those who are in this country should return or stay in their homelands- as though reigning in cultural and state boundaries have ever been a reasonable fix. So to put your Dictionary.com definition to use, the abnormal fear or hatred comes when the us versus them mentality is espoused as reasonable, because the "illegals" should "go back to their own country" because they're only legal to "go on welfare and be a drain on resources", to quickly summarize what was stated. So yes, that is xenophobia- a fear that the unknown and non-"American" person who is in the country.
But I understand that sometimes we all try and act as authorities on concepts we do not quite understand. Along with online dictionary resources, I would recommend doing some reading on citizenship, nationalism, and the state to understand why this is xenophobic and not simply "misinformed", focusing on authors such as Jyoti Puri, Benedict Anderson, Geoff Eley, Ronald Suny, and Anthony Giddens.
