No, I'm saying that Hanks did the scene as it was presented in Chaikin's book, and that his doing so is insufficient grounds for condemning him as anti-Christian.
Oh, you also deduced that it must have been Aldrin's fault that this story got out (and it couldn't possibly be an anecdote by Armstrong or someone else "dramatized" by Chaikin).
When you read the description of Aldrin taking communion, it's definitely written from Aldrin's POV, as it describes Aldrin's thoughts in some detail, while it presents what Armstrong's expression and body language looked like, and nothing of what his thoughts were.
Did they play it as Armstrong "not getting" Aldrin's desire to take communion or not? That has to be percieved by believing Christians as disapproval, whomever you ascribe it to originally.
As to Chaikin writing from "Aldrin's POV," that is totally under the control of the author and, without attribution, you cannot ascribe the source as having been Aldrin without other evidence. Your assumption is logical, but totally unprovable. It is only your assumption. I may choose to think taht Chaikin (or Hanks, for that matter) chose to structure it that way for their own purposes. There is absolutely no evidence to contradict either supposition.
