Henry Stevens is a conspiracy theorist, pseudoscientist, Holocaust “skeptic”, self-proclaimed “WWII expert”, and the founder of the “German Research Project” (GRP) to research Nazi UFOs. We are, in short, at the deep end here.
The GRP, according to itself, “researches and documents UFOs built by the Germans during WW2”, an idea that according to Stevens is – but of course – suppressed by the American government because, well, you know, that’s what they do. In particular, Stevens claims not only that governments lie and cover up secret technologies, including UFOs invented by the Nazis, but that Hitler survived WWII by moving on to a secret underground base in the Antarctic. He has accordingly written some books on these issues (published by Adventures Unlimited Press). He has also written quite a bit on electro-propulsion (anti-gravity) mechanism devices and various other forms of pseudoscience as well, as blithely ignorant of reason, reality, evidence or fact as you’d expect.
Apparently, according to rationalwiki, he also posts as “fivepercenter” on web forums, where he offers gems such as the observation that “[l]et me tell you the reason you cannot ever get a list of victims totally anywhere near 6 million. It is because that figure was pulled out of thin air, whole cloth,” concerning the Holocaust. In 2013, he was made a moderator on the forum Bonesandbehaviours, where he identifies as a “race realist” and advocates “scientific racism”.
Diagnosis: Thank you for playing, Mr. Stevens. Now go home and do something useful with your life.
