Opposition to an amendment doesn't make the point moot. The constitution was designed with change in mind. A change to the amendment is well within the the power of the government. I also do not agree that owning a gun should be right by any mean, but that is more of my own opinion on the matter which I've mentioned a few time before.
In most cases a lot of the countries that practice strict gun laws do not outright ban them in every circumstance. The law simply stipulates that there are just very few situations where owning a gun is warranted.
Most of the discussion you are referring to has already been discussed and proposed in Congress. Its just the gun lobby would choose not to discuss anything that takes away their "right." I would say that because of that extremist point of view much in the words of tacocat in your previous thread on this topic. Since they don't seem to want to take any middle ground then what choice does anyone have, but to oppose them entirely?
I think our points differ in our views on the second amendment, and its constitutionality in modern day society.
My point is not that changing an amendment is impossible theoretically, it's that the path a repeal of the 2nd amendment of the US Constitution is so far from the realm of possibility in the current political climate (and will be for the foreseeable future) that acting as if supporting a repeal is actually contributing to gun reform is more of an argument in how the constitution works rather than gun reform.
