You also mention that questioning the moon landings is akin to "smearing one of humanity's great engineering achievement". I get that. That is why I try to tread lightly. I know this means a lot to many people.
I want to clarify that moon landings, Apollo program or space flight in general are not sacrosanct topics which cannot be criticized. We can debate whether they are good use of tax payer's money, are they the best way to make science or what Apollo with today's technology would be.
Smearing which I loathe is efforts of some unnamed entities to cherry pick parts that look weird, parts that look wrong for layman's common sense and (un)healthy dose of bald lies and omission to create hoax narrative and then monetize that by patreon supporters, website ads or selling magazines, books, DVDs and other paraphernalia.
Second form which I loath almost as much are those who want to be something special and accomplish that by pushing others down. Apollo was scientific, management, engineering, manufacturing and Cold War propaganda success story which was founded on talented individuals who accepted mortal risks, sacrificed their family lives and some even their lives.
On the other hand people who have genuine questions about Apollo or space flight in genereal are heartily welcomed. Answering their questions gives opportunity to talk about the thing we are interested about. And it gives satisfaction when someone clears they misconceptions, thank you and either stay to learn more or walk away little bit wiser.
Unfortunately you don't act like the third type. You seem to have preconceived idea that Apollo was faked and when your concerns get addressed, you don't thank for new information and rethink your attitude. Instead you just ignore it and raise another concern. And another. And finally complain that the discussion won't stay in one topic.
