#4: Cheap Russian propaganda - they are not Nazis, they fought against Stalin's bloody regime

• The Latvian legion was
  formed in the winter of 1943 however; March 16^th 1944 is the
  day   the Legion was founded when Hitler
  ordered it be established.   All
  Latvian writers agree that the day marks the only time, the two Divisions
  of the Legion (15^th and 19^th) were fighting together
  against the Red Army.  Therefore, by
  making the 16th March a day to remember war dead,  Latvians,  (despite Latvian official protestations
  to the contrary), are making the day 
  when Latvian volunteers fought in the 15^th and 19^th
  divisions of the SS an act of commemoration.  As Israeli/Jewish critics have commented
  even if one takes the stance that the Latvian legionnaires were not
  criminals and that they were forced to fight for the Nazis, to commemorate
  the Legion is far from being a positive act.
• It should be noted that
  nearly 130,000 other Latvians - enlisted to fight against the Axis
  (Hitler's Germany, Mussolini's Italy and Japan). Most of them fought in
  the Red Army that liberated their country from Nazism. After the
  negotiations among the Allies, Latvia, like other Baltic states, was absorbed
  by the Soviet Union.  Professor
  Vaira Vike-Freiberga sixth president of Latvia from 8 July 1999 – 8 July
  2007 has described the men who joined the Red Army as traitors.

• 
  Nearly 80,000 Jews, or 90 percent of Latvia’s pre-war Jewish
  population, were killed in 1941-42, two years before the formation of the
  Latvian Waffen SS unit — which some Latvians claim shows the unit could not
  have played a role in the Holocaust.
• 
  But an
  unknown number of Latvian Waffen SS soldiers were involved in the murder of
  Jews as auxiliary police — years before they entered the front-line unit.

 "Vaira Vike-Freiberga sixth president of Latvia from 8 July 1999 – 8 July
2007 has described the men who joined the Red Army as traitors."

Please, keep in mind that Vaira Vike-Freiberga also described the concentration camp in Salaspils, Latvia, as a mere police prison where children were "cultivated through work".

For info: During World War II, the Nazis established Stalag-350-s, a camp for Soviet prisoners of war, in Salaspils. Two km outside of the city, in the nearby forest, the Nazi SS also established the largest civilian concentration camp in the Baltics.The total number killed in Salaspils concentration camp was 101,000 people, including children.

Believe your heart and mind, not what Latvian officials may say.
