Yes, I watched it, it's irrelevant to the discussion we're having.

Irrelevant because you said so? Of course it is relevant. Immigration policy as it pertains to legal and illegal immigration is and will increasingly be an important, political issue. Add to Beck's 1 million legal immigrants annually another 500,000 to 1 million illegals and you have exponentially increased the impact of Beck's numbers on his charts.

Specifically, what "strawman arguments" about immigration are you referring to? The hard data are there in terms of the validity of the numbers.
