The short answer would be anything which violates the 4th or 5th amendments does not need to be answered.
See I am not a lawyer and I solved the question in one sentence.
Lawyers today could not make a pimple on the a$$ of the founders.
The founders created a new type of foundation for a vastly superior government in about 18 pages whereas today's lawyers needed 2900 pages to just socialize 1/6th of the economy.
Because the USA was so successful, and some part of human nature seems to abhor success, the socialists/communists/Marxists/progressives HAVE to crush us and get us to fall in line with their failed system of government. We were, and I stress WERE, way too successful and we were showing up the statists for the failures that they have always been. This can not be allowed to stand in their minds.
We need a revolution to get back to the Constitution and not to have to be a lawyer to figure out if we need to answer a question on a census form.
If a census form is this complex in the legal world how the hell do we get out of bed in the morning without violating some federal or state law?
Today "IGNORANCE OF THE LAW" should be a perfectly valid excuse. Seems to work for scum like Rangle and Geithner.
The detail in the analysis is not an accurate presentation of the language in the law.
