Then we’ll agree to disagree.
The SS uniform is universally recognized as a symbol of Nazi atrocities. Whether or not they personally committed any atrocities, everyone who wore the uniform took an oath to Hitler.
If the marcher’s message is only to honor those who fought and died for Latvia, it is lost on the rest of the world because of their inclusion of foreign Nazi regalia.
Would the RAF and USAAF uniforms be a symbol of the atrocity visited on the innocent civilians in Dresden? Germany was a defeated nation by February of 1945 and Dresden had no military significance. Roughly 22,000-25,000 Germans died in one night, but I guess they were all Nazis, so that makes it ok.
