Online debate can be a great sport a for spectators and one that lets novices and pros to play in the same game. 
Not only that, but to be perfectly fair, at the core of most every Apollo hoax claim is actually the kernel of a good question. Why 
don't the stars appear in the Apollo pictures? Why 
didn't their suits puff up like Gemini's, and how 
did they operate their cameras while wearing them? Why 
do the distant lunar mountains look so close?
The deniers may not accept that perfectly good answers exist to all of these questions, but those who do can learn quite a bit. I often describe deniers as people who use questions as weapons, not as tools for learning answers.
