Just another reason for me to perform self-censorship on a daily basis. I'm a natural born citizen, but something tells me that looking at your family tree to find foreign blood ancestors isn't that far off the mark. I can see it now "You had an ancestor from (insert country here) back in 1764, you are now classified as a terrorist threat due to your foreign blood." Which is silly because almost everyone in the US has foreign blood somewhere in their back ground.
Ah! The joys of living under a totalitarian government regime.
