Why Doesn't the Gun-Obsessed NRA Send Volunteers to Fight ISIS?

Why Don't American Militias Volunteer to Fight ISIS?

Why doesn't the NRA  make itself useful for a change? If ISIS can recruit fighters to go to Syria and Iraq, why doesn't the NRA stop its useless chatter about protecting our democratic values from the presumed threat posed by our African-American president and send volunteers to fight in real battles?

How brave the NRA must feel, having its members march through Walmarts with loaded weapons. Admittedly, the only danger they face is from accidentally shooting one another.

The strategic complexity of the fight against ISIS is such that it would be inappropriate at this moment to send in the Marines.   But I see no reason why our gun-toting patriots in the NRA and Cliven Bundy's militia can't take their weapon-wielding patriotism to a real fight. Or is all this "open carry" business nothing more than a shield for cowardice.
