Well, while the book might be crap, and therefore it would seem sensible to wipe out the crap before it hits the public fan, I think there is a rather problematic tendency at work here: Avoidance of crap.
All Buddhist traditions and organizations operating in the West seem to do this. They seek to isolate themselves from all crap. They cannot handle any crap. They avoid the crap. This is utterly harmful tendency, and will lead into Buddhist Institutions isolating and fossilizing themselves. This tendency seems to come from Asian Buddhism, it must be added. The outcome of this is that Organized Buddhism will become fossilized, irrelevant and meaningless, as can be observed from Asian countries. Dead formalism is the future of all the existing Traditions, if this tendency is not countered in time.
Just look at the various issues raging in the Buddhist World. Sex scandals of many Tibetan High Lamas, Karmapa-issue, Diamonway-issues, FWBO-antics, Zen-lineality-issues, Soka Gakkai Pure Land issue, and whatever. There seems to be a general unease with handling these things, as they seem to be just crap and crappy issues. If there is a troubling issue, when have you seen the disputing parties share a space and admit that they do not agree? To even agree on the disagreement, and accepting the opposing points of view, without the other becoming "the other"? When have two practitioners continued to treat each other as practitioners while simply agreeing that there are some deep issues and rifts between, and then nevertheless continued to practice together? Whenever crap comes, people avoid it all, by distancing themselves from the other party, or throwing the other party away. There is no dialogue there, only two monologues shouted with megaphones over the fence, for a fence there is, never a shared space - sometimes even literally, as we know. Then "our party" is clean, and over the fence there is just dirt, crap, faults, and confusion. No need to talk after that, is there. This is the current situation of Buddhism. We all isolate ourselves into our own little compartments.
Because we Buddhists cannot live with crap, we are crap ourselves.
