(1) mostly, somewhat, has our best interests in mind, not totally, but somewhat, and
(2) not only uses fake accounts and taps lines, but has presence and/or influence at pretty much any major company like Google, Facebook, etc.
I think the right thing to do is to:
* Periodically speak up and support privacy legislation, semi-anonymously. (They can find out who you are, but don't be blatant or overly noisy, even from different accounts or locations, because that is more of a threat. Don't use Tor, Redphone, etc.)
* Realize that we have limited to no privacy when anyone can post info about you and credit card, phone/GPS data, etc. can be used/stolen.
* Know that there are politics, power trips, psychosis, and evil.
* Know that most people feel the same way you do. They don't want people killing their families and friends, and want to respect your freedom. Whether they are in government, military, or not, they are 99% trying to help. If you have family in government and military, think about them. They have your best interests in mind, usually.
I think it is fine to have these posts, but don't get too worked up about them. There is no reason to be paranoid. Just do your best with the knowledge you have, and don't act like a straight lace or a wierdo and you'll fit right in and probably won't be a victim.
If you join the militia, sell your house and build a bomb shelter in the woods full of guns, or start using cash-only without a recent purchase of a Dave Ramsey book, that's a red flag. Also, don't buy fertilizer in bulk, or from a bunch of different locations. Basically, don't be a moron.
