Calmly and intelligently explaining the reasons private gun ownership is beneficial and necessary has done precious little to preserve the right. It will be no different for the defense of personal privacy.
The solution to government attempts to erode personal privacy is two-pronged:
1) build tools to protect privacy, and
2) poison the hearts of the people against government secrecy
If no privacy for us, then no secrecy for you. Full stop.
God bless the leakers and whistleblowers, especially the ones who've been persecuted for it.
