Yes, we atheists are neither citizens nor patriots, George.
Your father though, oh boy, what a guy.
Real patriot. Real hard-working, exemplary American citizen. Let's see what he did for his country:

- A director and shareholder of companies that profited from their involvement with the financial backers of Nazi Germany.

- His business dealings, which continued until his company's assets were seized in 1942 under the Trading with the Enemy Act, has led more than 60 years later to a civil action for damages being brought in Germany against the Bush family by two former slave labourers at Auschwitz and to a hum of pre-election controversy.

- Even after America had entered the war and when there was already significant information about the Nazis' plans and policies, he worked for and profited from companies closely involved with the very German businesses that financed Hitler's rise to power. It has also been suggested that the money he made from these dealings helped to establish the Bush family fortune and set up its political dynasty.

- The firm he worked for, Brown Brothers Harriman (BBH), acted as a US base for the German industrialist, Fritz Thyssen, who helped finance Hitler in the 1930s.

- Evidence shows Bush was the director of the New York-based Union Banking Corporation (UBC) that represented Thyssen's US interests and he continued to work for the bank after America entered the war.

And that's just scratching the surface.
