@TMW - Heh "a responsible adult, and an above-average marksman" Yeah, and you're probably an above-average aeronautics professor too.
I think when people say there isn't a double standard in that interpreting the 14th amendment as applying to everyone, and not interpreting the second amendment as extending to every situation what they mean is that the constitution, all of it, is being interpreted in the context of prevailing social norms, and in that respect, both of these amendments are, unlike you, equally affected by...well reality. To make my point I need to appeal to the exact wording in the US constitution; "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed." The way I see it, there are two reasons why a well regulated Militia would be necessary to the security of a free State.
1) To protect your country from invasion. When the constitution was written this was a concern. But the US now has one of the world's largest standing armies, most technologically advanced, and most highly funded standing armies in the world, and massive reserve forces as well. If the US invades, unless you enlist, you're not gonna get to use that gun.
2) And this seems the most important one, so that the people can rise up and overthrow an overly tyrannical government, and so that such an overly tyrannical government could not impose it's will on the people by force, because they would also be armed and be able to fight back. But if you actually think this is ever going to happen, you're completely out of your mind. Essentially what you're talking about here is overthrowing the government and replacing it with a paramilitary junta. Even if that weren't completely nuts, it's still not any kind of a solution.
Essentially what my point is, is that if you don't see you, or anyone else ever using a firearm for either reason then you have to admit that social conventions have changed to such a degree that a literal interpretation of the second amendment no longer makes sense. Unless you think the redcoats might land at any second, or the government will confine everyone to forced labour camps at a moment's notice, there really is no reason why you should need to carry a concealed weapon in public, and you doing so would have absolutely nothing to do with maintaining a well regulated militia to protect a free State. Furthermore, the only well regulated militias that exist nowadays are the police force and the army, and the national guard, and it is not necessary for members of these organizations to supply their own firearms, a circumstance that the authors of the second amendment (who, as we know, lived before the industrial revolution) could not have foreseen.
You, carrying a concealed semi-automatic has nothing to do with any of this, you just think you just have a hard-on for guns. And as I recall the amendment does not say "Concealed semi-automatic assault rifles being awesome, the right of the people to keep and bear arms shall not be infringed".
The 14th amendment on the other hand (I'll paraphrase this one) is clear that it applies to all citizens, (and like it or not, the prevailing notion is towards recognizing gays as citizens seeing as there is no legal basis for concluding otherwise) and states that they should be given all the same legal protections as everyone else (and despite nonsensical protestations that marriage is a religious deal, simply because sometimes priests perform them, marriage is quite emphatically a textbook example of a legal protection). Case closed, end of story.
