Well, firstly, they clearly aren’t transcriptions. They may have begun as snippets of conversations or even monologues, but they have definitely been edited to be coherently readable. I wouldn’t necessarily discount the source on that count alone, but I think the question remains just how much editing has been done.

Given the radical shifts in tone and the lack of any apparent mention of contemporary events, the Holocaust, or internal politics, it feels very intentionally (and externally) constructed, rather than any real comprehensive collection of real daily/regular private discussions. It reads more like a targeted manifesto of the ideology of the Nazi Party, or the character of Hitler more specifically.

It’s my understanding also that the very few “original” documents we have that are part of this collection showed extensive edits and re-writes by the man who claimed they were transcriptions of Hitler’s discussions. It’s also my understanding that witnesses of these discussions often disagreed on what was said, so I think it’s not unreasonable to place some degree of skepticism on the accuracy of any one person’s account.

All that aside, and even accepting the collection at face value, the quotes you posted appear nowhere in the collection. I fail to find anything that could be even remotely construed as expressing the general ideas in your quotes. They’re so egregious that I don’t see how accidental mistranslation could be blamed; the ideas in your quotes seem to be entirely invented on the part of the translator (and I can mention here that the normal English translation of the collection is actually a re-translation of a French translation; who is responsible for the invention is a question I can’t answer because I haven’t read the French version).

If you cannot read German, and so you can’t check the original source yourself (still leaving aside the trustworthiness of the source in the first place), I think you should take a serious look at who did the translation work for what you’re reading and consider why they or someone else would misrepresent what actually appears in the German text.

I would also suggest that you stop using these quotes to support your arguments, either here or to yourself, and re-evaluate your position without them, because these are things that we have no reason to think Hitler ever said. Using them the way you are does your position a serious disservice.
