The website doesn't use the terms “Nordic Aliens” or for that matter “Aliens”, because it doesn't have anything to do with the original story.
But the term does have its own position on the website, assuming of course it originates from 'George Adamski' and 'Howard Menger' and not 'David J. Skal' - under Other Contactees#Frauds.
Frauds like George Adamski and K. Michalek, etc. have driven many people into delusion and misery. Adamski was not a contactee, as well as not Michalek or the South African, Elizabeth Klarer, nor H. Menger.
It is possible to prove that they are deceivers but one shouldn't try that, for the Earth-human can only be convinced of the truth with great difficulty. Their consciousness-based intellect is too low for that. One day, they will have to find the truth themselves, and only then will they take it in as knowledge. At the present time, the individuals who are the least agreeable to recognise and disseminate the truth should be those who had allowed themselves to be deceived by deceivers and charlatans for decades, and who had sacrificed millions for the dissemination of the stories of lies and books of lies. For them their world would collapse because they would have to recognize themselves as deceived and would have to disgrace themselves in front of the public.
