This book is the best synopsis of why the hoax is bullshit. Based Kollerstrom gave up his professorship to write it. He said he set out to disprove deniars and ended up one himself. The guy's a forensic chemist so he triggers shills hard, they'll stay out of this post or only enter to try to ad hom based Nick. All goats should read it, I didn't know you could get the PDF for free but giving shekels to Nick is the way to go if you ask me:
More sources for this book:
I haven't read them all but another you can get for free is "Giant with Feet of Clay," just by jewgling it. Dr. Kollerstrom does give a good synopsis and also quotes/references other authors. He tends to focus on the chemistry involved with the "gassings" and how, if it happened, the "gas showers" would have an abundance of evidence since Zyklon B becomes embedded in walls forever and gives them a distinct discoloration, which all the clothing delousing chambers have to this day as would be expected, which none of the "human gas chambers" have.
Just one glaring piece of evidence on a mountain of evidence that it never happened.
He also goes into detail on the enigma decrypts and how (((they))) tried to keep those classified forever because they include hundreds of thousands (millions?) of messages all over the theater, including in and out of the camps, and not one message about any systemic killings. Not one. But many messages admonishing commanders for allowing prisoners to die and to get the prisoners healthy. Most people don't realize that the allies were intercepting everything. The Germans thought their code was unbreakable so they were broadcasting them all over, including for all messages in/out of all the camps: not one message showing anything but that they wanted to stop typhus, and similar shit. This is actually one of the best parts of the book.
I'm trying to encourage people to actually read a book, not study fucking infographs and memes. None of that shit contains a fraction of the arguments in just one decent CODOH book, Kollerstrom's especially.
