:: I did not say that getting a letter to the editor published "disqualifies the mention of the whole thing".  Please re-read my comments earlier.  That would establish minimum WP:V and WP:RS basis to challenge Erlich's writings; whether that results in removal in toto, or just rebuttal on that specific point, remains to be discussed based on what specific details Olidort does or does not put on the record, and whether Erlich responds.
