Why is it double standard to point out that this is argument vs. argument?
Strawman: I never said pointing out that this is "argument vs. argument" was the double standard.
I said it before and I'll say it again: The double standard lies in your acceptance of your own arguments without evidence but the requirement of others to back their arguments up with evidence.
(btw, all debates, including scientific, is "argument vs. argument". You might as well say "people are talking".)
Opinion is evidence? Fascinating.
Strawman: I didn't say "opinion is evidence", although it sometimes may be, depending on the nature of the claim (your discussion with Tricky re: Hal, for example). In this particular case, I'm referring to authoritative sources on the history and meanings of words.
Arguments from authority are perfectly valid when the source is, in fact, an authority on the subject in question.
There is nothing in the mainstream consensus definition that exclude undeclared atheists as atheists.
That would depend on your definition of "undeclared atheists".
However, this argument is a
non-sequitur : Whether or not the mainstream consensus definition excludes undeclared atheists as atheists has no bearing on the question at hand. The mainstream consensus, in fact,
does exclude the possibility of infants, who lack the capacity for rational and abstract thought needed, being atheists.
Apparently, this is not an "argument vs. argument" issue after all. This is an "argument vs. numerous logical fallacies" issue.
