I think you should look back over the past 235 years, and examine the freedoms people enjoyed in countries where the constitution has changed, and in countries where the constitution has not been scraped and rewritten.  While the United States Constitution is a dynamic and evolving document, it does not change opinion every four years. It can be read, and understood, it is not subject to using a guise to hide its intent, in the style that many dictators have used to bring about their power. Many Americans, including myself, take comfort in that security of freedom.
As for what kind of person I would be, well I would probably be a British subject for starters, and who knows where the world would be today had 13 colonies not decided that enough was enough, and showed the world that people were meant to control their government, not the other way around.
My handgun does not infringe upon your liberties, unless you allow your fear of being assaulted by someone with a gun to overcome your love of liberty. There are two ways people handle this choice. Some face it squarely in the eye, and go out ready to face it, others chose to enact laws and restrictions so that they may hide behind an illusion of security.
I have yet to know of anyone who made it out of this world alive, and I don't plan on it. That said I'm not planing on being on my knees when I go either. (with apologies to TR)
