A quote from Mein Kampf...and there are more...<quoted text>
According to your link WW2 was a religious war, along with the Russian pogroms of 1905-06 and 1917-22 among others. Sorry, the information posted on Google answers isn't even close. Events like the pogroms and the holocaust weren't religions fighting but acts under atheism.
According to real historians, the Crusades, the Inquisition and with witch hunts killed approximately 200,000 people. And that's over a five hundred year period. Just looking at three of the greatest atheistic killers, Stalin, Mao and Hitler, there were 25 million + under Stalin, 12 million + under Hitler and about 70 million under Mao. That's over 100 million over a 45 year period. Add in others like Lenin, Khrushchev, Brezhnev, Pol Pot, Hoxha, Ceausescu, Kim Jong-il we add additional millions to the list.
Compare that to the religious events that some like to bring out. The Inquisition killed about 2,000 people over a period of 150 years. The witch killings? Contemporary historical sources put that figure at about 100,000 and again over more than 100 years. Crusades? Again, casualties on both sides totaled under 40,000. And that was over a period of almost 200 years.
The worst religious event killed about 1,000 people per year. Atheism killed 6,000 people per day.
It isn't even close.
"I believe that I am acting in accordance with the will of the Almighty Creator: by defending myself against the Jew, I am fighting for the work of the Lord.."
