I agree the form of oppression is becoming more subversive and deceptive. We try to stop it through the official system, but occasionally it moves fast enough to require a louder response to draw attention. People protest. They are met with police action, despite the 1st Amendment.
Now, when your protests become too huge to beat back with pepper spray, batons, gas, and non-lethal rounds where does it go from there?
Violence begets violence and if those in power refuse to relinquish it when the people demand it you will get a "hot war." You can't have the IRS harass everyone. You can't spy on every person to blackmail them.
Then I didn't understand the point of your post. If guns aren't effective in a specific situation, then don't use them. They will remain effective for the situations where they are useful though, so there's no need to toss them away.
I see a couple of points of separation between one of the more common rationales (ability to fight government oppression) for gun ownership and the prevailing realities. In that way, to me it borders on the religious - if all else fails, quote "the book".
Current reality would suggest that the things that are more likely to keep the government "honest" do not include guns, and to consciously or subconsciously think that things are ultimately in check because the people are armed is kind of the equivalent of a religious person not bothering to be moral because "God will forgive". If you're not doing what is effective, you're doing nothing. Psychologically, resting on false assurances must be damaging.
Further, considering that doomsday preppers exist I'm sure that some people have guns for the sole reason of being equipped to fight an oppressive government, but I'm also quite sure that most guns are owned for reasons such as self-defence, sport, hunting, and criminal needs. I find it a bit silly to own a gun for self-defence but justify the ownership via that specific constitutional rationale, and plenty of people do that. Removing criminal needs, as I don't think that anyone argues gun rights based on that, all of the others have points of justification. Whether or not another accepts those points is another matter, but sticking to the logic and not just resorting to quoting "the book" is a much more honest and forthright way of going about a discussion/argument. But for some it's like them trying to explain the benefits of no sex before marriage, but when all else fails falling back on "cause God said so".
To be clear, I wouldn't consider these to be the approaches that I see from many/any of the mainstays in this thread. Sadly though the "flybyers" are possibly more representative of the general population in both the negative and positive attitudes in regards to gun rights, and that's a problem. Where I might point the finger at some of you guys though is in differentiating between a negative and a questioning type. That
@Duke (Edit: oops, Kent) recently suggested I was completely insincere is a perfect example of that.
I was always open (albeit a little course), and I'd like to recognise
@Keef and
@a6m5 for the way that they helped me along by teaching, and not judging, respectively. I'd do a cheers emoticon, but I don't drink beer.
