This is exactly right, and what the original comment was describing I believe. Although I wonder if the subject is muddied as the adjective may be applied to the wrong noun. Their _skepticism_ is likely genuine and sincere, but their _engagement_ is not in good faith and is disingenuous. One problem, I think, is that it the communities are self selecting. Skeptics who engage in good faith on well understood topics become converts; all who remain over time in the community of skeptics are those who do not engage in good faith. It's a worthwhile question to ask why they don't engage in good faith, which I think has a more complicated answer than either straightforward ignorance or malice.
