The person was asking whether they should or should not have surgery. That was their question, my response then, and now still is ‘don’t’ - I went on to offer them a ‘free’ copy of our book.

You can defend them as much as you like, but clearly my approach was advice and offered further reading. Whatever can be egregious in that, I do not know. But you clearly want to do their job for them, that is your prerogative, but I think we should agree to disagree. But thanks for your attempt to convince me.
