Atheists; what do you base your morals on?

[Angrboda]

Just a quick note here. The argumentum ad populum or appeal to consensus is not a fallacy if the validity of the proposition is in fact necessarily dependent on or indicated by the will or opinion of the people (such as is argued here, by atheists). It is only when the will of the people itself does not logically necessitate the validity of the proposition that it is a fallacy.

(example, "The majority of practicing cosmologists subscribe to the big bang theory. Therefore, the big bang theory is the scientific explanation of the nature of the universe's origins." Practicing cosmologists are the relevant scientific community, and the consensus of the scientific community determines what is the accepted scientific theory, therefore, while the appeal is to consensus, it is not fallacious. Whether morals are properly a legitimate subject to be decided by consensus or not is exactly what is at issue, so the cry of "argumentum ad populum fallacy" lacks proper foundation to be made in this matter.)
