[Adonai One]

I believe reasonable assumptions can be made from book summaries, titles and the respective reputation of the author.

Assumption is the mother of all fuckups.
So you rather base your opinion on secondary sources like a summary than the source itself?

Again shoot first and ask questions later. If it can be challenged and removed without anybody providing proof that it is reliable, it should be. Material can always be restored. Tell me, why should material that is potentially misleading remain?
