Marko, I say "hurt America" because illegal aliens are creating a divide among Americans, I don't mean it from an economic stand point, although what their doing does not help.
American law and ldeals we legal citizens have worked, and died for, are being treated with great disrespect and shoved right into our faces. Groups like ANSWER, an anti-American group also drive these protests, and fuel racism, and anger among Americans to achive their own results.
Just look at gun control for example, these radical anti gun groups have created a great divide in modern day America simply over guns.
