There was also the ethnic cleansing and the creation of a racially pure hegemony.
Ethnic cleansing is effectively what's happening to Europe's native populations, but specifically we are focusing on the UK.
This ethnic cleansing comes as mostly the consequence of Britain's world wars and the subsequent rise of international liberalism in the west (both economic and social). These were choices made by post war leaders (especially the 60s onwards) and they are highly unlikely without the wars.
Some try to say they would have happened anyway, but a good counter-point against that is Japan, which maintained a healthy nationalism despite its far more heavier defeat and didn't use the naturalisation of foreign labour to rebuild its nation....despite, and it's an important point, despite being far more economically and infrastructurally destroyed.....because that's always used as an excuse.
Also I think there's some confusion with this idea that Hitler wanted 'racially pure hegemony' because there was already racial hegemony in Germany and Europe. That wasn't under threat of changing.
No, what he wanted (which would be a given once had he beaten the Soviets) was Germanic supermacy in Europe and he knew that to ensure that he needed to defeat internationalism, first in Europe and especially in the financial sector. His end point was in 'living space' for Germans mainly at the expense of slavs in the east.....Who were to be ethnically cleansed....Horrible.
Nothing to do with economic political spectrum but certainly thoughts the alt right are echoing today.
The 'alt right' (a term not really used today in the DR)....like all other political groups isn't one cohesive entity that agrees. This idea that the DR or 'alt right' to use your description are echoing Hitler or these ideas is off by some margin.....this is a common refrain of the left....and common in boomer circles even on the mainstream right.
For example, nothing I believe nor want requires Hitler's ideas. Hitler wasn't concerned about a Germanic majority continuing to exist in Germany.....he would have viewed the very idea of that being under threat as absurd.
I consider myself idealogically in the DR and I've never met or communicated with anyone who ever suggested that Britain should start attacking other nations to advance some cause as Hitler did.
No, that worldview is actually the reserve of neo cons and western liberals who wish to keep the Ukraine war going due to a hatred of Russia (and other reasons)......Not being pro Russia is sensible, but to waste tens of billions on continuing war instead of looking for a negotiated settlement is pretty aggressive.....Yet it's framed as justified, as all war-mongers obviously justify their actions.
None of that comes from the DR....or dissident right.
Also the Nazis wanted to murder the Jewish population in Europe and no one in the DR wants to murder Jews, indeed right wing Jews are part of the DR and it's their safety that is under threat from the liberals and left's (and economic right) idealogy to import non Europeans into Europe.....that's where the main hatred of Jews comes from today. Not the DR.....If there are any Nazi groups operating who call themselves part of the DR movement that can be disowned. I view that as antithetical to anything good.
Enoch Powell fought against the Nazis and was against their ideaogy (and a critic of US policy which he correctly described as wishing to replace the British Empire and thus worked for British decline) yet he also fought against the foreign displacement of Britain's native population. To be against the latter does not mean you support Germany ruling Europe (which happened anyway) and murdering Jews. It's a non sequitur and nothing to do with us.
Even if you look at fascists who ruled Europe's countries at around the same time as Hitler such as Franco or Mussolini (who was a prominent communist before being a fascist) you don't see this hyper hatred of Jews, that was a fixture of National Socialism and a result of who they blamed for losing WW1.
It's a part of National Socialism, not of the modern DR movement across Europe and more importantly here.
But the left don't care because lying about their opponents: as lying is in their DNA.
