I don't know what their position is either, but "arming up" isn't going to do anything against a modern, relatively competent military. Back in the time the second amendment was written (as an example) there wasn't that big a disparity in the resources the military could use and normal people. The citizens were less organized but had numbers on their side.
Today, there is absolutely nothing you can do with a gun vs drones, bombs, planes, etc. The only way you really prevail is if the government isn't willing to slaughter its own citizens and guns aren't helping there at all. In fact, the opposite may be true since it makes it easy for the government to label the people shooting at their officials as terrorists.
