Do you think that taking precautions against terrorism isn't useful,
& is just paranoia?
I don't see it as an either/or question. I think some precautions are useful for government to take against terrorism, just as the average citizen might consider taking useful precautions against possible government malfeasance. Sometimes governments do bad things. In fact, most governments throughout history (and even in the present) are pretty bad - even if our government is some kind of outlying "exception" of purity and goodness. I don't agree that it's paranoia to believe in the possibility that our government could turn bad.
But on the other hand, it's incredibly foolish for the average citizen to believe he has much of a chance to defend himself if the government was hellbent on getting him. No defensive measure taken by a person of average means could ever hope to defend against the massive apparatus and manpower the government has at its disposal. That's why the terrorists, cartels, gangs, and similar organizations operate as they do, almost like separate governments unto themselves.
I speak of the general intent to do this...not every stupid thing
government does, eg, putting babies on the no-fly list, or sexual
groping of children.
In a way, government does give a blank check to its servants which allow for the kinds of abuses you mention here. This is why many people are afraid and even paranoid about the government. Not because of the stupid things they do, but because of stupid people being given a modicum of power which they are inclined to abuse/misuse.
I think government completely ignores my friends....except
perhaps for the occasional eye roll.
Well, even that's more than what most people would get. For most people, the government just sees them as a number, a statistic, a single dot on a page. As long as you don't let your drivers license expire and you're never late paying taxes, Big Brother would be far too bored to even take a quick peek at you, let alone watch you.
This is true even in authoritarian countries. As long as people just do as they're told, not make waves, keep their mouths shut, stay out of the government's way, and blend in to the background, then they have very little to worry about - even if the government is pure evil.
But the paranoid types you're referring to seem to be just the opposite. They go out of their way to let the authorities know about their legal rights and claims, whether it's about the use of public lands, possession of firearms, whether or not people have a right to drive without a license - they're the ones who draw attention to themselves.
