I would bet the number of Americans who believe this tripe are fewer than 20% of the population.
LOL. You give way to much credit to the American public. I’d bet <10% understand how email, servers, backups, etc. are handled.
Even on a level of basic understanding, the NSA scandal uncovered by Snowden proved that what we do and say is never private or unrecoverable. I would think the people of this country would at least understand that, but perhaps I’m woefully optimistic of this nation’s intellectual capacities.
