on table talk, from what I have found on wikepedia:

"Controversies

Although considered authentic, contentious issues remain over particular aspects of the work, including the reliability of particular translated statements within the French and English editions,[5][14] the questionable manner in which Martin Bormann may have edited his notes,[11][15][16] recommended caution using the Table Talk as a historical source,[17][18][19] and disputes over which edition is most reliable.[5][6]"

"Historian Richard Carrier maintains that much of Trevor-Roper's English edition is actually a verbatim translation of Genoud's French, and not the original German.[9] Carrier shows that a textual analysis between Picker's original German text and Genoud's French translation reveals that Genoud's version is at best a poor translation, and in some instances fraudulent.[5] Many of the quotations used to assert Hitler's anti-Christianity are derived from the Genoud–Trevor-Roper translation. Carrier cautions that no one "who quotes this text is quoting what Hitler actually said."[5]"

Further, on table talk:

"Carrier states that Hitler does indeed criticize the Church and various Christian dogmas in the Picker and Jochmann text of the Table Talk. For example, Hitler argues against belief in the physical resurrection of Jesus, in favor of a spiritual one. Carrier suggests these criticisms are only directed at Roman Catholicism and the institutionalization of religion generally. Historians Richard Carrier, Werner Jochmann, and Richard Steigmann-Gall state that Hitler was certainly religious, citing him expressing a belief in God, divine providence, and Jesus as an Aryan opponent of the Jews.[5][11][20]"

Also, It is a false dichotomy to claim that it is either the christianity or atheism. Attempting to show that he was anti-christian, which is clearly in dispute, does not show he was an atheist.

Also, his actions speak louder than words, he managed to kill a lot of people, (not christians), and conquer everything in sight. If he was so anti-christian he sure did a poor job of showing it for a guy who had no problem killing everyone else.

But more on your favored book, which shows once again that he was not atheist:

"Steigmann-Gall, in his study on the Nazis' attitude towards Christianity, states that Hitler's criticism of Christianity in the Table Talk, if reliable, reflects a newly formed anticlerical attitude which began in 1937. Steigmann-Gall suggests that this change might have emerged as a result of Hitler's frustration over his failure to unify all German Protestant churches.[20] Despite his private rupture with institutional Christianity, Steigmann-Gall emphasizes that Hitler continued to hold Jesus in high esteem, considering him to have been an Aryan fighter who struggled against Jewry.[20] In Hitler's view, Jesus' true Christian teachings had been corrupted by the Apostle Paul, who had transformed them into a kind of Jewish Bolshevism, which Hitler believed preached "the equality of all men amongst themselves, and their obedience to an only god. This is what caused the death of the Roman Empire."[30] The Table Talk also shows he continued to wish for a united Christian Church of Germany.[30][31]"

I would also suggest finally, that if hitler was an atheist (he wasn't) it says nothing about any other atheists.
