I don't see how that's really relevant to literally anything.
The crux of Greenwald's response:
"Given that I had never written about Sam Harris, I found it odd that I had become the symbol of Harris-bashing for some of his faithful followers. Tweeting a link to an Al Jazeera column about Harris and saying I find one of his quotes revealing does not make me responsible for every claim in that column...That said, what I did say in my emails with Harris - and what I unequivocally affirm again now - is not that Harris is a "racist", but rather that he and others like him spout and promote Islamophobia under the guise of rational atheism."

edit: by not relevant, I mean that Sam Harris's opinion of Greenwald doesn't mean that Greenwald has indefensible opinions.
