This is more complucated than it looks. It does not help that, in recent years, when making news reports on aniversaries, or documentaries about, the Second World War, there is a tendency to speak of 'Nazi' bomber squadrons or 'Nazi' tank battalions. When I was young, they were always described as 'German'. It seems to be an effort to place the blame for everything on the Nazis, and to exculpate other Germans.

The facts, unfortunately, give the lie to this. Only a minority of Germans were ever convinced, hard-line, card-carrying Nazis. They tended to join or be inducted into the SS formations. The majority of Germans who fought in the war srved in the Wehrmacht, Kriegsmarine or Luftwaffe and were not Nazis. Not Nazis, but Germans who felt that the war was justified, either to pay back the French, recover Germanys' stature a a Great Power, or to stop Communism.

There has been an attempt to sweep the fact that a majority of Germans supported Hitler under the carpet. When one adds in some 20-40 yearsof Post-War European politics designed to "keep the Germans down and the Russians out", one can see the reasons why this sudden back-pedalling is taking place.

That said, however, the idea of re-enactors wearing Wehrmacht or Lufwaffe uniform would not be too much of an issue. Civil War re-enactors dress as both Cavaliers and Roundheads in the UK. In the US, re-enacitrs dress in Brtish or Confederate uniforms without causing problems.

The issue here concerns SS uniforms, specifically. The SS was the armed wing of the Nazi party. Originally recruited as a security force, they were later expanded into an elite force of racially-pure and politically-indoctrinated soldiers. They provided Hitlers' military bodyguard, front-line combat units, the Einsatzgruppen, who rounded up Jews and other 'undesirables' in occupied territory, and concentration camp guards, A lesser-kown group were the Waffen-SS, who were a kind of Foreign Legion, recruited from racially-acceptable populations of non-Germans, such as the Nordland and Wiking regiments recruited in Scandinavia and the Britische Freikorps (also called the Legion of St George) recruited from British PoWs). Apparently the group causing the trouble were wearing Waffen-SS insignia and appeared to view the war on the Eastern Front as a crusade against Communism (a key reason why many people joined those formations).

Now, SS uniforms have been illegal in Germany since the War, but can be obtained, along with other reproduced Nazi paraphernalia, on the internet. They can be recognised from ordinary German uniforms by the insignia, specifically the 'SS' runes on the collars and the swastika armbands. Wearing these uniforms would be offensive and upsetting to Jews, LGBTQ+ people and many people of Eastern European descent who suffered at the hands of the SS. Waffen-SS uniforms can be considered even more offensive, as the people who wore them both embraced Nazism and in many cases could be considered traitors.

I'd certainly find them offensive, and I'm very far from Woke!
