I feel like the people in this thread saying you should ask for personal details are kind of missing the point of the ‘nothing to hide’ argument. It’s not that they feel they have nothing to hide from everyone, it’s that they feel they have nothing to hide from those with access to their data (governments/corporations). Knowing intimate life details of someone you know personally is very different from knowing intimate life details of some random person you’ll never meet. I would argue something like this instead:
Unless you’re a newborn, everyone in the US has broken thousands of laws in their life. It’s unavoidable. If corporations/the government have records of all that, if people don’t have privacy, the powers that be have the power to put anyone and everyone in prison for the rest of their lives at their discretion.
Even if you’re not worried now, once your data is out there it’s not coming back. You may agree with the policy of government and corporations now, but can you be sure that’ll be the case in ten years? Twenty? Thirty? Who knows how laws and regimes will change, and through all that, they’ll always have power over you.
It’s not unreasonable to answer yes to that first question; that’s why it’s not the most sound argument. I was pretty firmly in the ‘nothing to hide’ camp for a long time because that was the only reason I heard. I really don’t care if some random government office worker knows about all the intimate details about my life. I don’t mind if you know I’ve been having prostate problems, but that’s not something I would tell to someone I know personally.
