I agree with what you say until you imply skepticism is bad, or that skepticism is at odds with appreciation. I can appreciate and be thankful for research even if I don't trust it or have further questions.
It's not the skepticism. It's the lack of perspective. You can be perfectly balanced and skeptical, but your readers will not necessarily take away your perspective if you don't provide some amount of contrast/consider different opinions. If you only post skepticism, readers will just always be salty -- and it really sets the tone of discussion for the future.
Is it really fair to interpret the parent comment to say "you cannot appreciate or be thankful for research if you have further questions"? Or was this just super deadpan and I got wooshed :)
I wasn't trying to joke, but I might have whooshed is GP was. I doubt it though.
