America is a nation of sovereign citizens. All have agreed with Washington that “the Constitution is sacredly obligatory on all”.
Muslims are forbidden by their Koran from becoming Americans. Therefore, Islam, being antithetical to and irreconcilable with America, can lawfully be banned from America.

However, were I to claim a belief in the Great Cannibal, and believe that the Great Cannibal commands me to eat my neighbor without his permission - then my religious belief would require my being banished from America.
Islam Delenda Est - because they WILL make us play Cowboys & Muslims.

After the Know Nothings have successfully banned the moslems ... how are the Catholics (or other selected scapegooat) to defend themselves? Should the Knights of Columbus trade in their swords for AR-15s?
