There's a difference between a skeptic and a debunker.
A skeptic will simply evaluate a claim against the evidence provided. If the evidence is ambiguous, the claim is not accepted and the object remains unidentified.
A debunker works from a belief system that the claim and the evidence are just 'bunk' and tries to present an alternative claim that fits the evidence. This claim is sometimes called an 'explanation' because a debunker feels a need to educate the general public which is all too gullible and to expose the people who abuse this gullibility. If the evidence to that alternative claim is disputed, however, a debunker tends to get annoyed because their belief system in under attack.
I must say that calling this site 'metabunk' does not do it justice, because the debunkers in UFO history often pushed ridiculous alternative claims that did not even remotely fit the data, and they got away with it because both the press and scientists did not bother to check.
At least this site does a better job of checking their alternative claims against the data. Sometimes an old-school debunker pops up in the discussions with an outlandish claim and he is treated with healthy criticism by Mick as well, which is refreshing.
The data is there, for instance on http://www.nicap.org/onlinebooks.htm. Or read the French Cometa report, English translation available at https://www.narcap.de/dokumente/COMETA-Report-englisch.pdf
But you know what they say about bringing a horse to the water...
No, there's really no difference whatever between a skeptic and a debunker. Both take the scientific and logical position that the burden of proof is 100% on the person making a claim of something out of the ordinary. Extraordinary claims require extraordinary evidence. A skeptic isn't simply a 'disbeliever' or someone neutral...a skeptic is someone who says 'where is the actual evidence for your claim ?' and who looks for alternative explanations just as much as any debunker would do. ALL claims are 'bunk' by default unless sufficient evidence exists. That is how science works.
