All religions represent a code of moral behavior. The exact code varies between religions. Atheism rejects this code freeing one to replace it with something of the atheist own choosing. As evil people in power usually desire evil things they naturally regard religion as a direct threat because the moral code of most religions would condemn whatever it is they plan to do. Atheism is simply a void which leaves an empty space to be filled. Everyone lives by some sort of general principles if only simple personal expediency. This void leaves the atheist highly vulnerable to whatever unhealthy substitute moral codes are in vogue at a given moment. Eighty years ago the concepts of Lebensraum, Rassenschande, and Untermensch were in vogue in Germany.
Christopher Hitchens arguments on Hitler are quite disingenuous. Hitler was a first rate demagogue he said whatever was necessary to solidify his power and advance his goals. As in all things you need to look at what he actually did.
The Case Against the Nazis; How Hitler's Forces Planned To Destroy German Christianity
http://www.nytimes.com/2002/01/13/weekinreview/word-for-word-case-against-nazis-hitler-s-forces-planned-destroy-german.html?pagewanted=all''The Persecution of the Christian Churches,'' summarizes the Nazi plan to subvert and destroy German Christianity, which it calls ''an integral part of the National Socialist scheme of world conquest.''
In the 1920's, as they battled for power, the Nazis realized that the churches in overwhelmingly Christian Germany needed to be neutralized before they would get anywhere. Two-thirds of German Christians were Protestants, belonging to one of 28 regional factions of the German Evangelical Church. Most of the rest were Roman Catholics. On one level, the Nazis saw an advantage. In tumultuous post-World War I Germany, the Christian churches ''had long been associated with conservative ways of thought, which meant that they tended to agree with the National Socialists in their authoritarianism, their attacks on Socialism and Communism, and in their campaign against the Versailles treaty'' that had ended World War I with a bitterly resentful Germany.
But there was a dilemma for Hitler. While conservatives, the Christian churches ''could not be reconciled with the principle of racism, with a foreign policy of unlimited aggressive warfare, or with a domestic policy involving the complete subservience of Church to State.'' Given that these were the fundamental underpinnings of the Nazi regime, ''conflict was inevitable,'' the summary states. It came, as Nazi power surged in the late 1920's toward national domination in the early 30's.
According to Baldur von Schirach, the Nazi leader of the German youth corps that would later be known as the Hitler Youth, ''the destruction of Christianity was explicitly recognized as a purpose of the National Socialist movement'' from the beginning, though ''considerations of expedience made it impossible'' for the movement to adopt this radical stance officially until it had consolidated power, the outline says.
Attracted by the strategic value inherent in the churches' ''historic mission of conservative social discipline,'' the Nazis simply lied and made deals with the churches while planning a ''slow and cautious policy of gradual encroachment'' to eliminate Christianity.
The prosecution investigators describe this as a criminal conspiracy. ''This general plan had been established even before the rise of the Nazis to power,'' the outline says. ''It apparently came out of discussions among an inner circle'' comprised of Hitler himself, other top Nazi leaders including the propaganda minister, Joseph Goebbels, and a collection of party enforcers and veteran beer-hall agitators.
Of course, the churches stayed in Hitler's good graces for only as long as the Nazis considered their cooperation expedient. Soon after Hitler assumed dictatorial powers, ''relations between the Nazi state and the church became progressively worse,'' the outline says. The Nazis ''took advantage of their subsequently increasing strength to violate every one of the Concordat's provisions.''
In 1937, Pope Pius XI denounced Nazi treachery in an encyclical that accused Hitler of ''a war of extermination'' against the church. The battle had been joined on some fronts. Nazi street mobs, often in the company of the Gestapo, routinely stormed offices in Protestant and Catholic churches where clergymen were seen as lax in their support of the regime.
Still, in a society where the entire Jewish population was being automatically condemned without public protest, care was taken to manipulate public perceptions about clergymen who fell into Nazi disfavor. ''The Catholic Church need not imagine that we are going to create martyrs,'' Robert Wagner, the Nazi Gauleiter of Baden, said in a speech, according to the O.S.S. study. ''We shall not give the church that satisfaction. She shall have not martyrs, but criminals.''
But once they had total power and set off to launch a world war, the Nazis made no secret of what lay in store for Christian clergymen who expressed dissent.
In Munich, Nazi street gangs and a Gestapo squad attacked the residence of the Roman Catholic cardinal. ''A hail of stones was directed against the windows, while the men shouted, 'Take the rotten traitor to Dachau!' '' the outline says, adding: ''After 1937, German Catholic bishops gave up all attempts to print'' their pastoral letters publicly and instead ''had them merely read from the pulpits.''
Then the letters themselves were confiscated. 'In many churches, the confiscation took place during Mass by the police snatching the letter out of the hands of the priests as they were in the act of reading it.''
Later the same year, dissident Protestant churches joined in a manifesto protesting Nazi tactics. In response, the Nazis arrested 700 Protestant pastors.
Objectionable statements made by the clergy would no longer be prosecuted in the courts, the Nazis said. Statements ''injurious to the State would be ruthlessly punished by 'protective custody,' that is, the concentration camp,'' the outline says.
