There is an argument, spread by those on the right that the National Socialist German Workers' Party, i.e. the Nazi Party were socialist. But they were not. Looking back on the interwar history of Germany, while they initially spoke against big business, they were against the works of Marx. I had posted on this back in 2017 but back then, I had forgotten the support that Nazi Germany gave to fascist Spain in the Spanish Civil War with The Condor Legion, support recorded by Pablo Picasso on canvas when it comes to the bombing of Guernica.
In addition to the support for the right wing forces in Spain, once in power, Hitler and the Nazi party cracked down on socialists resulting in many being sent to Concentration Camps where they would be allocated red triangles to distinguish them from other prisoners. I have seen threats against those on the internet who criticise the far right on the internet, a concern as if given the chance, I am sure they would lock people like me up for my political views.
This has been brought up again due to a right wing revisionist. I may be being unkind as they may not be aware of history as opposed to trying to rewrite it.
