National-socialists were socialists. They celebrated the 1st of March worker's day together with other socialists, signed war pacts together with other socialist countries to "free non-socialist societies" and in general did about the same as any other socialist dictatorship, including mass murder/deportation of million humans as something normal.
Then comes the obvious: the founder of socialist ideology called fascism was for several years a die-hard socialist. In fact, was the chief-editor for socialist "news" during several years in a row. Similar to Stalin's career path with Pravda.
A few years down the road in power, socialists understand that socialism doesn't work and change. Same for the soviets, same for the cubans, same for the chinese, same for just about any socialist regime. They were all socialist, they opressed people just like all other socialist ideologies. Neosocialists today still try to disguise previous socialists regimes as "it wasn't real socialism".
It was socialism kind sir. We had enough of it here in Europe.
Thank you, but no thanks.
