If you're going to accuse someone of using "racist epithets", you should quote the source -- not opinions of random reviewers on Amazon. I assume you've actually read the book, and are not just recycling other people's opinions...
You take "Anglo-Saxon philosophy" as a racial slur? Really? Here's a crazy thought: maybe it actually refers to Anglo-Saxon philosophy -- i.e.
analytic philosophy, as opposed to
Continental (humanist) philosophy.
But hey, that would mean the authors were educated people making a subtle point (cryptic, even!). Not likely -- so let's assume they're xenophobic assholes instead.
Isn't this the kind of ethnocentrist dogmatic narrow minded thinking that the OP was discussing?
No. It's a book written by European cavers about technical ropework, as practised in European caves, with European rigging methods. It should not be surprising that the authors prefer techniques that have proven to work in that context, and that Marbach himself helped develop.
ACT does in fact discuss American methods, particularly with a view to creating a hybrid frog/ropewalking system. The authors acknowledge their own limitations:
The purpose of this book is not to discuss every American technique in minute detail; others have already done this, and their authors were quite knowledgeable on the subject. Our perspective is more or less that of an outsider, but it is interesting nonetheless for us to have some understanding of these techniques.
Here's another statement from this "dogmatic" and "racist" book:
Only time will tell. If it ever happens that one climbing method comes to reign supreme, it will likely be a similar compromise between the two principle techniques [i.e. American and French].
