Asking questions is a fair and responsible part of being a smart critical human being. However, questions in of themselves are not a form of evidence nor is the construction of potential doubt.
The problem with this debate is that in order to even begin to question the moon landing you must discredit NASA as a valid source of information. Once you discredit the major source of almost all known space travel information, then you're left with this information less void where any anecdotal side note carries as much weight as a NASA document.
