Are these people really so dense that they believe countries should not have borders?  What kind of country just allows anyone to move in anywhere anytime?  It is a felony to enter Mexico illegally.  What if we treated every "undocumented" alien as a felon in the US?  I hate the way they move here illegally and then tell us what our laws should be and how they have a right to this and that in our country.  It's like me moving into their house and demanding dinner and complaining about the service!
