Calling an illegal immigrant an "undocumented immigrant" is like calling someone who is breaking and entering into your home an "undocumented tenant".

This is coming from a person who believes illegal immigrants are not worth our time or money to prevent and, if we werent a welfare state, I'd be pushing for open borders.

@freemo are you quoting somebody else there? Or is this your own opinion?

@freemo An 'undocumented tenant' is a squatter. Squatting unused property is enormously beneficial both to the squatters and the larger community they interact with. It helps alleviate pressure on housing and can bring different kinds of diversity to an area. It is especially good in terms of fostering creative projects and especially arts.
If one believes the most important aspect of communities is private property and rent-seeking, then such a person would obviously object to squatters, but for such a person the entire notion of community is secondary to seeing power at other's expense.
Of course, this metaphor completely falls apart in terms of migration because the US is not private property and migrants tend to hold jobs and pay rent and taxes. The tax monies collected from all migrants, including undocumented ones, exceeds the amount of tax money allocated to programs that benefit them.

@freemo Calling someone 'illegal' is dehumanising and using false statistics to to aid scapegoating is a step further. While crops sit unpicked in California and the US is the relative freedom of LGBT people a cornerstone of its justification for aggressive foreign policy, the obstacles put in the path of asylum seekers and migrants generally are not helping anyone at all.
This ideology has a name and I'm afraid it's extremely unflattering.
