Every since the primaries, I have had more people approach me asking where to begin their education on preparedness than I have for all of time prior to the primaries.
While prepearedness should be a way of life for our generation, as it was for our grandparents and great-grandparents, unfortunately, in many cases it is not. The thought processes that go along with "the mindset" are often overwhelming to many newbies, and they tend to panic and lean towards the "what guns do I get!?!" mentality.
Firearms are a tool. I would rather see a newbie get a reliable .22 and several thousand rounds of ammo for a few hundred dollars, and make other preps, than see someone run out and buy a top-of-the line HK, AR or FAL and 200 rounds of ammo.
Along those lines, people should be charitable before, during and after a crisis, and you simply cannot do that if you cannot take care of you and yours FIRST.
With that in mind, an excellent place to start on the internet is http://www.survivalblog.com/.
If you are still convinced that you MUST learn everything about guns, begin with Boston's Gun Bible. While it cannot cover everything, and it has a lot of opinion in it, it is a good read and quite logical in many areas.
Good Luck, and don't let the Bastards grind you down.
