Unfortunately we're now using the word skeptics for 2 totally different things - questioning dogma with sound reasoning and reasonable first principles - trusting one's own belief against overwhelming evidence of the contrary.

Galileo squarely belongs to the former, while flat earthers and moon landing 'skeptics' belong to the latter. Let's not conflate the two.
