If you would like an answer to that, then I would suggest reading the section titled "Being open to individual differences is not enough", and perhaps the quoted passage in the later section "Tasting the water you swim in". You're probably less "German" than she thinks you are, and more "German" than you think you are, but that's not incompatible with what she says. Don't mistake the blurb for the content. I agree that the blurb is a bit obnoxious, but then, its function is to appeal to (or piss off) someone enough that they'll pause and consider buying the book (maybe if only to prove how wrong it is). I have not read the book but I have heard the author speak on the topic, and in my opinion she adequately addresses your complaint. I personally still find her message a bit oversimplified, but isn't that what we're talking about? That's what you have to do in order to get your readers/listeners to understand what you're trying to communicate! Or do you? As in the original article here, there can be benefit to reading things where the author doesn't try to make it easy. Perhaps they put down the messy truth in disconnected fragments, or they pile up lots of examples that don't quite fit any simple orthogonal dimensions of explanation. Such compendiums incorporate deep insight to anyone willing and able to put in the effort to derive it for themselves. Let the reader figure it out by meditating on them, or rereading them 100 times, or trying them out in practice, or whatever.
