I've never seen anyone on FR advocate open borders or amnesty. And the only anti-war FReepers are the anti-illegals who oppose the war in Iraq.
A border guarded by 12,000 armed guards who arrest over one million illegal aliens annually, and routinely seize over 1 million pounds of marijuana and 15 - 20 tons of cocaine every year, is not an open border. We have not had an open border in almost a hundred years.
A guest worker program is not an amnesty. An amnesty is a pardon for criminal offenses. A guest worker program is an immigration program that grants temporary work visas to people who qualify for them.
The Antis cannot win an honest debate on substance so they have to change the meaning of words such a "open border","amnesty", "invasion", etc...
If the ILLEGAL aliens here are required to go back home and re-apply for a guest worker visa to re-enter the U.S. legally, that's fine with me. If they are here ILLEGALLY and granted a visa so they can stay/work here without paying any penalty, nor are their employers for hiring them ILLEGALLY, that is amnesty.
