With all respect but I firmly believe that most Christians won't be able to retain the basic value such as "love thy enemy" when it comes to some of the points illustrated in the article (see above link).
Neither do I believe that humans needed to be given the Commandments for it would be an outright lie to say that prior to the Commandments people didn't know right from wrong. How do we explain peaceful societies that are non-Christian?
Believing and acting upon are two different matters which are more often than not prone to clash.
