>The national security argument only flies if the people buy it. That's the root cause; fix the people.
You can't. People that are receptive to the politics of fear are that way because of brain structure; they simply are unable to respond to reasoned arguments.
I deliberately and provocatively overly simplify the issue here, but I claim that every problem we face can be solved by better education that simply requires people to ask "Is that really the way you say it is?" in every single step of every single fact they ever face.
