Sure. Point is, it's not necessarily hot air. These people are deranged and looking for a reason to shed blood. Recall that they wanted to get women and children killed last time. Recall the hillbilly cry session youtube video. That guy seems to legitimately think he won't be seeing his family in the near future. Why? Perhaps because he anticipates dying in a blaze of glory during a gun battle with The Man?
Don't underestimate the insanity of these folks. You grew up around them. You know they are 90% bluster (like most rednecks), but you also know there is a tinge of craziness there.
