>>304569/pol/ygamist here. I wouldn't be in the least bit surprised if we were more heavily armed than /k/. /pol/ has a lot more grown-ups than you think. 30+, 40+ and even 50+'ers are always coming out of the woodwork. These are the sorts of people who are likely to have guns, and more importantly, the money to spend on lots of ammo and a variety of survival guns.
Sure, a greater proportion of /k/ may be armed, but all it takes is one middle-aged paranoid anti-semite to outgun your asses.
