Mmm FGT I think maybe you are right about there being a difference between chat and N and P. I dont think it's a matter of bears with little or big brains, but maybe a different sort of interest? A different angle?
Talking to friends I am just the same. I know them personally, we "know where each other is at" politically, one often throws snippets of this or that in......
Of course N and P -especially after a long thread - can get like that, but there is a strong interest in trying to establish facts as far as possible, what's verifiable, what is rapidly changing and needs to be followed and so on.
Its simply a different kind of what is satisfying or meaningful to each one of us,
but there is nowhere except N and P for producing evidence and conclusions, evidence for speculating, and moving forward with it and then, if one disagrees, finding evidence to support the counter argument, going actually a-hunting for it.
which amazingly, can be satisfying......☺️
