@ofwarren in a perfect world absolutely, we'd be able to get rid of the idiots doing the derailing and carry on with adult, insightful discussion. (*perspective noted).
There's something about this case though that was having particularly nasty outcomes - one being ridiculous accusations against individuals close to NB; one being off-topic arguments about unrelated but highly emotive subjects; another being the level of vitriol from posters against each other for not agreeing or questioning their thinking.
None of those things are your fault, and none of them should mean that threads should be pulled automatically.
My thinking is just that the thread had really taken a nasty turn and was coming off the rails in as much as there was far more problematic and potentially damaging content than useful or even sane commentary.
I guess there is a line where a thread can be doing more harm than good, and my feeling is that that happened here.
Maybe that still doesn't make it right to delete it - but I understand why it would be deemed so, and broadly agree in this specific instance.
