What does "good faith" mean? Does it mean "honest"? For example, I, the real actual me, think that the US should vastly reduce the number of unskilled immigrants it admits, strongly secure its borders, tighten the eligibility criteria for asylum, and deport anyone found crossing the border illegally. However, on Facebook or LinkedIn I would never say this as I would get Francesca Viola'd. So it's actually my real name identity that speaks in "bad faith" and only my pseudonymous identities (on HN, Reddit, and in the voting booth) that speak in "good faith."
