Just rephrase it as "Keep the government out of my affairs". It's not just "protect my privacy" though, it's also "protect my ability to organize against the government", which in the US heavily overlaps with the second amendment and the rhetoric about it. In a more globally appealing version, you can spin that into various forms of "This is what the Communists did to prevent people from rising against them" (replace Communists with Nazis, if desired). Or reference V for Vendetta or 1984 or other cult classics.
