The point is that it is not a legitimate scientific question, as those posing it are disregarding all evidence for geological and cosmological causes for rapid deglaciation.

The YD impact hypothesis is motivated by creationist thinking (hyperbolically ”god threw a stone at us to relieve mankind of ice”) and the idea has been thoroughly refuted.

Clinging to beliefs when there is ample evidence to the contrary is the very opposite of the scientific method.

The original paper proposing a YD impact was serious science put forward by serious academics, AFAIK: https://pmc.ncbi.nlm.nih.gov/articles/PMC1994902/

That it was later a cause taken up by creationists is annoying, but it has no bearing on the scientific question (which is as yet unsettled).
