actually, that's not the consensus.
there were 3 1/2 million Jewish people in occupied Europe at the beginning of the war.
per Walter Sanning's Book, "The Dissolution of Eastern European Jewry"
http://www.amazon.com/Dissolution-Ea.../dp/0939484110
Sanning is a Jewish historian who uses census numbers from around the world to establish population numbers for the Jewish people before & after World War 2. He finds that 1.2 million Jewish people perished during the war. He also found a maximum of 3.5 million Jewish people lived in occupied Europe at the beginning of the war (and most of them got out while they could).
this little snafu in the Official Version of the Holocaust is related to the changing of the plaque at Auschwitz in the 1990's. It used to read, "in memory of the 4 million who died" - implying that 2 million died elsewhere. It was changed to read, "in memory of the 1 1/2 million who died" - so that if the Auschwitz casualties are added to the 2 million, you get ... 3 1/2 million.
that Jewish people were rounded up & killed is not disputed.
for example, Martin Gray's book, "For Those I Loved"
http://www.amazon.com/Those-I-Loved-.../dp/0451069420
Martin Gray was a young Jewish boy in Poland when the Nazi's walled it off. He started out by bribing Nazi guards and importing tons of food, which also turned out to be a profitable business. He subsequently was sent to Auschwitz, which he survived by hiding in the latrine.
I don't think Gray's book was fiction. Nor do I think Sanning has any evil intentions - he started out as a historian studying the 20th century & ended up writing a book that turned out to be very controversial.
Of course, if you look at the total number of casualties in WW2 - 60 to 100 million - the death of 200,000 to 3.5 million Jewish people places in dispute their claim that they suffered the worst.
It is tradition in America to paint Hitler as the Worst of Boogey Men. Given that the US killed about 4 1/2 million civilians in Southeast Asia during the Vietnamese War - and a few million civilians in Iraq in the last 15 years - who is the bigger Boogey Man, the US or Nazi Germany ?
As far as the German Bishop - "Williamson said he believed no more than 300,000 Jews perished in the Holocaust" - he might be in the ballpark.
The 2 people I cited - Gray and Sanning - are both Jewish. Neither is motivated by anti-Jewish goals.
