In German there is a nice expression "Bedenkenträgerei" which is used for what people do who rather express their worries about something being difficult, than open-mindedly contributing to finding a solution. These people try to clad themselves in seriousness, which however is based on fear and lack of imagination.
I try to find a good expression for this type of behaviour in English.
The relevant dictionaries do not help. In one dictionary I found "worrier" for "Bedenkenträger", that's for the person who acts like that. However, "Bedenkenträgerei", as a noun for this type of behaviour, has a quite more ironic or scoffing tone to it. My feeling is that "worrier" is not really scoffing.
So, what ways do you see to express something like that? May be a word, may be sentence - something that would be just spot on in English?
I thought of worriership. But does this sound well?
Here is the context: I was reading an article in The Guardian on a physical experiment with strong light being cast on water vapour to directly extract hydrogen from it. The comments area underneath was dominated by people who communicated truisms like that it is difficult to store hydrogen, and that liquid hydrogen has less energy per kilogram than, say, ordinary hydrocarbon fuel today. Bla-bla. I found this an idiotic 'Bedenkenträgerei', as, yes, these facts are well-known but are not relevant here, and I wanted to blame the contributors for... right... Bedenkenträgerei.
