Donation requests are different from other threads in that the proposition being ‘argued for’ in the OP, and the existence of the thread itself, are inseparable. So of course someone who thinks the request is ridiculous thinks the thread itself was a bad idea. This is why the notion of ‘threadshitting’ is quite simply a bad fit here.
If I open a thread in The Game Room arguing that Ed Kranepool was the best baseball player ever, there’s a big difference between disagreement (“Ed was a pretty good ballplayer for his time, but don’t be ridiculous”) and threadshitting (“why are you guys wasting time debating that silly game anyway?”) With donation requests, that gulf vanishes.
This isn’t a nail; put down your hammer.
You certainly include strange things as ‘arguing against the merits of a donation request.’ I wouldn’t characterize any of the above in that manner.
The second-to-last one qualifies, and the last one…well, that depends on the nature of the explanation.
Look, we argue all the time in the Dope about what adults should or shouldn’t be doing. In fact, listen to yourself:
You just told me what I should do. Aren’t you supposed to start your own thread for that?
It’s like the Knights of Ni finding themselves saying ‘it.’
But getting back to the point:
WTF?!
I have faith that Dopers can reach their own conclusions too, but debating the issue in question is part of that process.
But again, the problem is that an argument that it’s really pretty ridiculous for someone to even be asking strangers for money for air-conditioning for their rabbits or a European trip for their teen, is simultaneously an argument against the OP, and against the existence of the thread. They’re inseparable.
AFAIK, this is a unique circumstance. Using the hammer of ‘threadshitting’ under these circumstances says that normal debate about the issue set forth in the OP has to take place in another thread. This is true for nothing else. You are placing limits to disagreement with the OP in this context that you do nowhere else in these boards.
