Moreover acting as if you need to justify yourself (or your group) to others already represents a significant loss of standing.

boggled] Isn't that what we're all doing here at LW? Arguing and justifying our arguments? Did you just lower your standing with your justification? At time of writing I see quite the reverse.

LW is a freakishly abnormal social setting, even for internet fora. Most people here care more about figuring out what's true than winning arguments. This is unique in my experience of the internet. "facts" are not the primary use case for language., social politics are.
