I think of the 2A as a principle.
Then there are the ways, or avenues, or material things, which are fully consistent with upholding the essence of that principle.
I believe in no compromises whatsoever with respect to upholding the essence of principles, as best we broken mortals can grasp those essences.
So I don’t think the analogy of a spectrum of give and take with those averse to a principle is a valid analogy, because it completely disregards the inherent nature of what a principle is. From the git go, it frames a principle as not really being a principle at all, and perhaps that is in fact the strategy of such an analogy, or ploy. It throws the principle onto broken ground, and if you accept that frame of argument, well, you’ve already lost.
Concretely, with respect to the 2A, if you take the principle to be the right of the individual citizen to have the means to defend himself against organized tyranny, well then, limiting that defense to only allow semiautomatic long guns is already hollowing out the core principle to a significant degree given the armaments available to local authorities, should they target civilians.
On the other hand though, the deterrent effect certainly remains to support the principle, and that’s what we really want, right? I don’t want to ever have to use my firearms on any other human being unless all other options for me have been exhausted - and nobody here disagrees with that.
Always carefully assess the ground your opponent has chosen for a fight. Unless he’s chosen it very foolishly, you want to throw him out of it.
I agree with you on the 2nd amendment principle.
I think a good political parallel regarding compromise can be the abortion debate. You have the hard core who demand abortion be illegal in almost all cases, you have the opposite hard core who believe it should never be restricted, then you have the middle who want some restriction but not too much. Maybe a 15 week limit or a 12 week limit or 6 week limit. The problem for the die hard pro-life side is that if they get a bill proposed or a candidate picked in a primary who has that no-compromise position then you have a candidate who will alienate too many people in the middle. If that happens then their candidate doesn't get enough votes to win the general election and instead of a moderate republican who would push a 12 week limit, you get a democrat who might push a 20 week limit or no limit at all. End result is that you have more legal abortions by taking the harder stance than if the party took a moderate stance of allowing some abortions.
If I ran for office and came out with an uncompromising view on gun rights saying that all guns should be legal for all individuals, I might win a primary but then lose a general election because my position is too far right for the majority. End result would be legislation less friendly to gun rights. To put that in more practical terms I think that means we need to understand that some level of restrictions are necessary, even if we don't agree with them in principle, to keep the situation from going too violent to where public opinion starts to swing left and we risk losing even more rights. For example lets say a mentally unstable person/terrorist/gang banger buys a gun and shoots up a school, this sways public, they ask how that person could get a gun. In response we can take two options, consider some form of gun control, or stone wall saying we mustn't compromise. Stone walling is, I argue, bad for us on many levels, both optically and practically in terms of protecting out gun rights and addressing the problem so it is in our interest to concede certain restrictions on firearms (arms in general) to both protect our rights and address the problem of gun violence.
I don't really agree with the way some others paint the issue in terms of a compromise because they paint the compromise as only one side giving up something but that is looking at it only from their side. Simplistically put you could say one side wants no guns in their country, the other wants lots, the compromise is some guns, but sides are giving up something they want. On top of that I don't know that it would be that accurate to paint democracy as a compromise in the first place. Bills are made, votes are cast representing a population (in theory) and law is made. Compromise may have been made somewhere but the democratic process is not about compromise, it is about our voices being represented. Sometimes we don't get what we want because the majority wants something different and that doesn't mean we compromised anything, we just lost the vote. Yes I know enshrined rights are not supposed to be overridden by popular vote but that is a separate issue as I am only focusing on the use of the word compromise in this discussion.
There are all sorts of ways to try and control guns to affect the gun violence problem, registration, background checks, permits to purchase, purchase waiting periods, red flag laws, restrictions on certain types of guns, etc. I think we are best served supporting approaches that can have the maximum safety effect with minimum level of intrusion into gun rights.
