The reason for making it absolutely clear you're cut and pasting is embedded in the founding of these threads.
They started after the experience of being on MN during the Referendum campaign.
We were inundated with Brexit trolls. And they had a style, which could be summed up as fake news and word salad.
Red, in particular, would discuss why and how that was so corrosive to democracy and communication.
She suggested a style of posting in opposition to that. You'll notice she holds to that (though I admit I slip
): name your source; give information as to where it can be found - so that it can be verified by readers; ideally, give context (who this is, what is their status as regards verifiable truth); and Red often adds analysis, clearly separated and identifiable as such.
It all matters.
The style of those Brexit trolls was aimed at mixing truth and lies, until people were too weary to care which was which. And once that happens, political truth-based communication - which is a hugely important base of democratic politics - is utterly corrupted.
If the democratic populace is forced, cajoled or coerced into abandoning that base of democracy, the space is left for the enemies of democracy.
So, anyway, that's the thinking behind it and why some of us think it matters.
(I do wish we had taken some of Red's words on this and used them as a sticky. They were so thought-provoking. For me, anyway.)
