Attempting to goad a critical reviewer into engaging in some sort of comments-section "public debate" (assuming that somehow the public discussion would change the reviewer's mind) a _decade_ after the fact? That behavior is, in a word, insufferable.
EDIT: Also, "I know it was a challenge to review a book of its size..." comes off as insinuating that (1) the book is somehow "grand" and (2) maybe the reviewer didn't "get it".
