A funny irony about our "christian" nation

Ahh yes, America. Our blessed christian country. Good thing we pray to the right God here. You know it's quite funny how in America when we see those backward muslims in some dark corner of the middle east or central asia, stoning or whipping some woman in public because she might have had sex outside of marriage or engaged in adultery, we are appalled and shocked. We love to call the muslims out on how uncivilized they are or how backward and sexist they are, but if you consider that the christian Bible, says adulterers and unmarried women who've had sex shall be put to death by stoning and even worse set on fire alive.

So how can we "christians" be appalled when we see those in the middle east doing almost exactly what the holy scripture says they should do? It clearly says in the Bible that for a woman who enters a marriage in which "the tokens of virginity be not found...the men of her city shall stone her with stones that she die."(Deuteronomy 22:20-21) Wow. So the west has caught up with the fact that actually stoning someone today for having sex before marriage seems a bit extreme, but parts of the middle east haven't, and when they do so we criticize them for not behaving morally when indeed the holy Bible, the text for which this great country was(supposedly)founded on says to do just that which the muslims in the middle east are doing. So who are the hippocrates here?
