That's understandable although I believed it was evident in my syntax that it was meant to be funny. perhaps I misjudged. That doesn't answer the question about the nuke advocates.
So ranting "nuke 'em all" is a statement of sentiment, but, for most everyone, remains somewhere between an empty threat to a mere expression of anger. Not a realistic outcome, just hyperbole, and far less do-able than most of the garbage the DU crowd says should be done to Republicans and conservatively minded folk.
Taking a rifle to the border, by contrast, and shooting at illegals is possible for most anyone who is so inclined, and we wouldn't want to be the ones to be blamed for inciting such an act.
