We accredited the letter to a Mr. George R Zug, when in fact the article appears to have been written by a Mr. Steve Anderson. We must apologise for sub-par research when writing this article. The source we took the information from did credit Mr. George R Zug, and there do infact appear to be two copies of the letter now making their way around the internet. But as Mr. Cherfas pointed out, this one should be taken as a definitive.
Apologies to all readers.
