"doing the old "self determination for all peoples""
This is just a sugarcoated way of saying "whites" get to categorize everyone and decide where each category gets to live. In other words, "whites" actually rule the whole world and run it like a zoo.
""Hitler supported "non Whites" in their own countries!""
Which countries are their own countries?
Firstly, it is known that Hitler supported Amerindians taking back America from "white" rule, so Hitler did not consider America to belong to "whites". This can logically be extended to all lands stolen by "whites" during the colonial era, contrary to the WN position that "whites" get to keep all their stolen lands.
Secondly, it is known that Hitler opposed discrimination against "non-white" Germans in Germany. Thus he considered "non-white" Germans (ancestrally from former German colonies) in Germany to be in their own country. This can logically be extended to all origin countries of all the Western colonial powers, contrary to the WN position that these should be "white".

https://en.wikipedia.org/wiki/Colonization_attempts_by_Poland ). Hitler directly invaded Poland. Had the Third Reich won WWII, "non-white" Reich citizens would have been among those able to live in Poland afterwards if they wanted to, whereas they had been unable to do so before. Thus Hitler had no interest in keeping Poland "white", contrary to the WN position.
Finally, if Hitler did not support "non-whites" being in "Europe", then why did he prefer Charles Martel to lose, and why did he praise Andalus and disparage the Reconquista?
"what JAM based his ideology on"
During OWNP and Monarchist Party times, JAM officially declared that America should be multiethnic, and in private discussions expressed that "non-whites" from former British colonies deserved to live in Britain. I do not know what he believes now.
"I would prefer they abandon this and acknowledge (as many of the more literate identitarians are doing) that Hitler was an anti racist, and that it is in their interest to support Zionism/the Allied Powers. "
I agree.
"Of course this approach will also end up strengthening Identitarianism as it will give them a more coherent ideology, and I don't want that either."
An incoherent ideology is more dangerous in that, even after defeating it, the narrative of what was actually being defeated can be distorted again. Last time, Himmler and other racists in the NSDAP was what allowed the Allies to portray Jews as victims of racism, leading to all the subsequent confusion that we have had to deal with ever since. Do we want to go through all this again?
