As you have probably already figured out, what James says of Mormons is true for all proponents of religion:
Mormonism makes a staggering number of amazing claims that defy both common sense and the historical and archaeological records. It is up to the Mormons to prove that there is a reasonable, plausible explanation for every one of them.Have the Mormons met their burden of proof? Not hardly. The Muslims? Nope. The Catholics? Of course not. The mainline Protestants? Not even close.
We atheists don't need to argue unless we just really enjoy doing so for some reason. We can simply wait for the requisite proof. I don't know about you, but I'd be happy to believe should evidence sufficient to substantiate each and every religious claim arrive. Of course, this would render faith obsolete because religion would then become rational.
