This is a new short video by Dean Irebodd / Denierbud, his first in years. Previously he has made some long, highly detailed documentaries on the holocaust. They are some of the best on the topic from the revisionist perspective, and they can be seen at this page (search for "Dean Irebodd"):

I believe "Dean" is a tongue-in-cheek pseudonym (dean ire = denier) and that the way he speaks, saying everything with exaggerated contempt, is an intentional affectation to disguise his normal sounding voice, so that people would not recognize him by sound in everyday life and persecute him for making these documentaries.
