Say "Most sexual abuse is domestic. Shall we mandate cameras in every room of every house? Or remote engine-lock to stop terrorist car attacks? There are cameras everywhere, forensics is more advanced than ever, 'going dark' is the opposite of reality. But there is always some small remaining scrap of freedom left to sacrifice for supposed 'safety', until we are reduced to cattle. Doing so is spitting on the graves of everyone who ever died for freedom, of everyone who chose to fight instead of 'peacefully' submit to foreign conquest or domestic dictatorship.
But suppose you do prefer 'safety' to all else, to privacy and liberty. Suppose you want to sacrifice everything for it. Will you even get it? We can today build prisons and surveillance far more effective than at any point in history, and once we've turned society into a safe cage, how sure are you the wrong people won't get the keys? Historically, how many governments would you have trusted with such total surveillance of their citizens? Tsarist Russia? Soviet Russia? Present day Russia? Communist China? Present day China? Nazi Germany? The Stasi? The Khmer Rouge? The Ottoman Empire? Iran? The British Raj? But you're sure nothing like that will happen here? This time, benevolent government will last, and we can safely surrender all means of opposition?"
