The swastika myth has been exposed. Debunked is the claim that the swastika was used by Hitler as a sankrit sign for “good luck” and stolen from an eastern culture (or that it was reversed for "evil"). 

The myth began in translations of Hitler’s book “Mein Kampf” containing the only comments ever made about the symbol by the leader of the National Socialist German Workers’ Party (Nazis). Hitler did not use the word "swastika." Hitler used the German word “hakenkreuz.” The most literal translation is “hooked cross.” Most readers intuitively understand “hooked cross” or "crooked cross" or even “hakenkreuz,” but not “swastika.” There is no evidence that Hitler knew “swastika.” The word "swastika" as used in English for the symbol of the National Socialist German Workers' Party was a misleading translation of "hakenkreuz." 

In "Mein Kampf" Hitler gives little information about his selection of the symbol, but he states "a dental surgeon from Starnberg submitted a good design very similar to mine, with only one mistake, in that his swastika with curved corners was set upon a white background." Hitler in his own words states that the design was not enough like the hard-cornered "S" letters of the sieg rune as used also in the "SS" division. Some people have identified the dental surgeon as Dr. Friedrich Krohn, and they claim that Krohn's design also pointed in the opposite direction, which was changed to point clockwise by Hitler. Another source claims that many National Socialists accepted Krohn's design, but Hitler insisted changing it. All of the above shows Hitler's deliberate alteration of the original proposals into a specific goal-oriented symbol of "S" letters. 

Hitler's Hakenkreuz was not a swastika. A swastika can point left or right, and historically sits flat on one side in a square shape.

1. The socialist swastika's arms reach clockwise. Before modern times, the most common representation of swastikas was with arms that reached counter-clockwise. The reason that the National Socialist German Workers' Party turned their swastika's arms to reach clockwise was to highlight the letter “S” shape for “socialism.” 

2. The socialist swastika is turned 45 degrees to the horizontal. The reason that the National Socialist German Workers' Party turned their swastika 45 degrees to the horizontal was to highlight the letter “S” shape and line it up with the cross. In ancient times, the swastika is usually flat on one side in a square shape, not a diamond.

3. The socialist swastika repeats the thunder-bolt "S" characters commonly used for words beginning with "S" in other symbolism by the National Socialist German Workers' Party.

4. The socialist swastika resembles a rune from the ancient Germanic alphabet that corresponds to the letter "S" used as a stylized "S" in other Nazi symbolism. 

The "S is for Socialism" symbol is a mnemonic device today because a hackneyed abbreviation for "National Socialist German Workers' Party" is used exclusively by media and government schools so that most people who use the abbreviation do not know what the abbreviation abbreviates (National Socialist German Workers' Party).
