So...your misunderstanding of the term 'debunk' is, in some way, giving us a specific example? See below*.
Again, I ask you to back up what you said with EXAMPLES - let's try slightly different wording:
What, specifically, is your best example showing "..that it turns the debunkers against each other"?
Don't just handwave towards a youtube video - tell us exactly what you are referring to, with quotes and cites. BTW, I'm quite familiar with the Mythbusters look at the myth of the 'moon hoax'.. It was quite well done given the limited amount of airtime they gave it, and the fact that they aren't imaging experts or space scientists...
* And to help your understanding, I'm a debunker. I don't like BUNK (like the Apollo Hoax myth) and I do like to explain why/how the BUNK is wrong and that the folks that push it either:
- haven't a clue, but love to hear themselves talk
- want to make a fast buck from the gullible and uninformed
- are trolls...
