It's not a joke,.if you see how quick naI Germany found all the Jews in Holocaust. Us researchera said it would take a team of researchers 2 to 3 years to find all the Jews manually.
Germany was so quick because a few years or decades before there was a census made with the help of IBM machines, and all information was automatically processes to get Jewish addresses very quickly.
So a naive census done some years before, where everyone would have said "what's the matter" was then used to exterminate 6 million people.
Having your life constantly nowadays is all strategic info the next genocidal dictators in your country needs.
