So you support the entire social and cultural agenda of the left, including partial birth abortion and homosexual marriage, and you are honest about supporting the libertarian position of truly, opening the borders, here is their platform on that.
This is the actual, 2004 text of the Libertarian Party Platform on immigration.
COMPLETE PLATFORM TEXT
INDIVIDUAL RIGHTS AND CIVIL ORDER
IMMIGRATION:
The Issue: We welcome all refugees to our country and condemn the efforts of U.S. officials to create a new “Berlin Wall” which would keep them captive. We condemn the U.S. government’s policy of barring those refugees from our country and preventing Americans from assisting their passage to help them escape tyranny or improve their economic prospects.
The Principle: We hold that human rights should not be denied or abridged on the basis of nationality. Undocumented non-citizens should not be denied the fundamental freedom to labor and to move about unmolested. Furthermore, immigration must not be restricted for reasons of race, religion, political creed, age or sexual preference. We oppose government welfare and resettlement payments to non-citizens just as we oppose government welfare payments to all other persons.
Solutions: We condemn massive roundups of Hispanic Americans and others by the federal government in its hunt for individuals not possessing required government documents. We strongly oppose all measures that punish employers who hire undocumented workers. Such measures repress free enterprise, harass workers, and systematically discourage employers from hiring Hispanics.
Transitional Action: We call for the elimination of all restrictions on immigration, the abolition of the Immigration and Naturalization Service and the Border Patrol, and a declaration of full amnesty for all people who have entered the country illegally.
Try reading again. Just because the constitution doesn't give the feds the power to ban it doesn't mean I support it. Maybe you can point out the part that authorizes those powers for everyone here so we can clear that up.
I'm for getting rid of the departments of education, energy, and interior. That's leftest by you? Which cabinet level offices would you defund? And do you really want to go humping party platforms? The GOP doesn't even pay lip service to it's platform anymore.
Did you find the part where the LP gets rid of Welfare at the same time?
Imagine that ... no welfare ... nothing to keep them here.
On the other hand, at present, we give them Section 8 housing, food stamps, Obamaphones, tax credits, welfare checks, and everything else to KEEP them here and that's just at the Federal level.
Now let's look a little further. Who appropriates the money for all these welfare programs? Well that would be the Republican controlled House of Representatives.
Might I suggest the problem might be the Republicans who are in power as opposed to the Libertarians who are not?
Dude ... give it up. This is not a partisan argument you can win.
You're supposed to be attracting voters to your cause and your candidate, not telling them to get stuffed and go away. Doing that gets you Hillary in 2016.
