See my reply to "thizbuzz" in this thread for a very basic understanding of why I think having an intelligence agency makes sense at a basic level.
As for your mentions of karma, and my commenting on "throwaway" being in your name - you're right, I don't click through and check the status of a user before replying to their comment on this forum, or any other - because I'd rather reply to what they wrote. Was I tricked by the "throwaway" in your username? Absolutely - your plan worked as you desired. If you think this makes me lazy, so be it. I'd say you intentionally mislead me, because putting "throwaway" in a profile is a common convention on internet forums, and I absolutely just accepted it as is.
What does "American" mean to me in general? I'd say the founding fathers of our country made clear their intentions in the Constitution, and Bill of Rights. To me, being American at present means agreeing with those intentions - which encompass a lot of ideals about personal freedoms, and rights to privacy.
I think the current attitude of many branches of our government toward our rights to privacy is "un-American" - especially with respect to the NSA. I'm not going to write a treatise here on exactly what that means, however I think it should be self evident to those who have a good grasp of American history. In fact, I'd be willing to bet that recent immigrants who have achieved citizenship and taken the requisite tests might have a better understanding of the concept of what "American" ideals supposedly are than many native born citizens.
