To answer your question, I don't think it's unreasonable for you or anyone else to question the NSA at this point or even to assume they're lying. I think it's unreasonable for you to discount completely the possibility that they're telling the truth, and to denigrate anyone who accepts that possibility (like myself) as stupid. And I think it's wholly unreasonable to assert that the collection of bulk data, which is a complicated issue that, if it ever reaches the SC, is likely to result in a 5-4 decision either way, is the moral equivalent of child rape. That position makes YOU an extremist.
It is unreasonable to assume the NSA is telling the truth. It may not be unreasonable to believe there's a (however slim) possibility that the NSA is telling the truth, but it's insane to think that's the most likely scenario here.
"Moral equivalent" is a pretty silly concept. But if I'm ranking things on the scale of "how evil are they", governments spying on their own people is pretty damn evil.
We all get outraged when we hear of this exact same stuff happening in the former USSR, Russia today, and other dictatorships. No, timschochet, I'm not calling our government a dictatorship, but it does share some very striking attitudes about individual privacy with most dictatorships. It should be telling that everyone we've heard from in government on this topic has lied repeatedly. NSA officials, Obama, Senators, etc. have all blatantly lied. You know what? It's not excusable, despite what you keep repeating.
