I think permitting an OP like that to stand opens the door for all manner of “Just Asking Questions” type behavior for what are otherwise supposed to be (I thought, at least) impermissible topics (right up there with 9/11 trutherism and scientific racism). Or does that only apply to GD?
Because asking, “Hey guys, I’m not sure about this site, can you all please check it out and let me know what you think?” (my paraphrase, not an exact quote) is a common tactic in directing people to… *sources like what the thread in question directed people to, thus drawing in a wider audience and platforming such views while maintaining plausible deniability. I don’t know nightshadea’s deeply held beliefs, but I do know that if you start allowing people to “just ask questions” about sources that coincide with holocaust denial, scientific racism, 9/11 trutherism, etc., you have effectively declared those open topics for discussion on this board.
I will fight ignorance, but holocaust denial goes beyond mere ignorance in my book. Whether or not nightshadea personally picked up on the dog whistles or not, or how they happened upon that particular source, I cannot say. But any rule that requires first discerning the OP’s true intentions (rather than their impact or the content itself) is bound to be unenforceable, because most bad actors are clever enough at least to obscure their intent by, say, just asking questions.
*ETA: Think of it as like directing people down a rabbit hole. The first link is some dubious interpretations of history that seem awfully generous to history as a Nazi might want it told, and then the link within the link (the banner prominently displayed at the end) is to straight up holocaust denying material.
