1) This is just tin-foil-hat paranoia. You're crazy. (This is by far the most popular choice.)
2) I'm unimportant. "They" wouldn't care about anything I do, so what does it matter?
3) Universal surveillance is a fact of life now. Deal with it, or move somewhere remote like Kamchatka and raise your children to believe civilization was destroyed by zombies.
Sure, most people have no idea. Sure, most people are more worried about things further down Maslow's hierarchy. However, if we are to select a reasonable venue for informed discussion of the issues, this one isn't too far off the ideal.
Let's do our best then to try not to call people (1) crazy (2) paranoid, or (3) crazy who actually care about the issues, OK?
