Can we please close the borders, quickly?

You may have heard that there is a conference going on right now in Iran calling into question the existence of the holocaust. Not the severity, not the scope, but the very existence of it.

Anyway, David Duke, who Louisiana erroneously sent to the House of Representatives once in spite of his having been an Imperial Wizard of the KKK, is one of the speakers and had this to say:

"The Holocaust is the device used as the pillar of Zionist imperialism, Zionist aggression, Zionist terror and Zionist murder,"

Knowing this nut case is currently overseas, can we just all agree to close the borders and keep him over there? If we let him reenter we have passed up the opportunity of a lifetime to rid ourselves of this louse.
