There was nothing wrong with the parent comment. It would have been better to describe some of what's actually in the book, but it was still helpful information, obviously well-intended. I'm sure you didn't mean to bully js2 into deleting it, but please don't post like that to HN. There are kinder ways to ask for more information.
Oh, my apologies, I did not at all intend it to be taken like that.
I meant to say that while the book js2 linked is surely welcome information to have in this discussion, this doesn't absolve the OP of the burden to back the claims with something more substantial given how strong these claims are (and, as the thread shows, controversial).
