I disagree with you that flying is a "choice" that turns airport security into an opt-in procedure.
you can live your entire life and never fly. if you are a citizen of the world communicating inside the US (or internet traffic passing through the US), evidence seems to indicate that some portion of your communications are being recorded and stored under the pretense of fighting terrorism. everyone communicates. these are worlds apart as from each other.
Let's vote this gal/guy into office so we can have our rights suppressed in the name of freedom, said no one ever.
