I dunno about "survivalist" stuff. My K31 isn't going to keep me from catching avian flu. Been through three bad hurricanes, and never fired a round of ammo.
Actual survival is about common sense. When SHTF, you either have it with you- always- or you don't. Some not only don't have common sense, they don't even know what it is. Those are the ones that the stobor eat first.
Those fringe "survivalists" wierd me out. WWJS?

Sorry, I don't need any radioactive iodine pills today. No gas mask either. I'll take my chances.
Now the fringe marksmanship organizations... well, anybody who encourages gun ownership, marksmanship and the responsbility that comes with it... is doing a good thing, generally speaking.
I just don't care for the political extremism on some of those sites. I wish extreme views of any kind would stay away from the shooting range. You see what religious extremism gets us... a return to 13th century barbarity. So much for the advancement of the human race.
Can you imagine being so intolerant you can't take a joke? Would you want to kill someone who drew a cartoon you didn't think was funny?
Can you actually believe that in today's world, there are millions who would do so?
Maybe the survivalists aren't that crazy. At least, by comparision.
