Not wanting to fill out an intrusive form like this for no good reason, divulging personal history and other sensitive information to the government, does not make you a "paranoid conservative". It is the prudent thing to do. Setting aside the fear of the government having such information on you; how much do you trust their information security? The census information would be a treasure trove for social engineers. Rather than saying "paranoid conservatives", you should say "people who aren't fucking idiots and weren't born yesterday". Political affiliation has nothing to do with desiring privacy.
