A: "I have nothing to hide."
B: "Give me your bank details."
A: "Not like that! That's not something to hide because I'm hiding them to protect my savings."
B: "The reason other people hide things is also to protect themselves, their property, and their loved ones."
As Mitchell and Webb pointed out, "identity theft" is actually bank theft that's blamed on the account holder. https://www.youtube.com/watch?v=CS9ptA3Ya9E
Notwithstanding any legal or ethical judgement, being burglarized would cause me significant inconvenience and at the very least some sentimental losses, even if I were ultimately compensated years later with interest. Therefore, I keep my keys private to protect myself.
I told my father something about myself years ago and he tried to make the case that I hadn’t brought it up because I was ashamed.
I wasn’t ashamed. But if you share certain things about yourself, being gay being one of the most obvious examples, some people want to define you by it, or talk about it to the exclusion of all other things. I’d much rather talk about trees, for that matter tax law.
One of my mentees had a bit of a persecution complex about several things, orientation one of them. When late in our relationship I finally mentioned that my kid had come out, she was shocked I hadn’t brought it up before (which in retrospect I think she may have been recalculating her opinions of me on the fly, like the Key & Peele skit, “Oh I see, I’m just an asshole.”)
Without a pause I answered that it’s because it’s not the most interesting thing about them, which just made the eyebrows go up even higher. But I think it finally sunk in.
If I were focused on that meaning, I'd call talking about whether they're doing right or wrong things completely unresponsive. We're talking about privacy and protection, not their personal assessments of the merit of their private lives.
Instead, I'm going to give them the benefit of the doubt and remind them that the people who are dangerous to them may not share their standards or ethics.
Better would be to not use that phrase as most people have something they wish to remain private or secret, without it being anything sinister. Like their password for example !
By implication, what your provider knows, governments also know - they have a direct line.
