According to Margaret Thatcher: “The truths of the Judaic-Christian tradition are infinitely precious, not only, as I believe, because they are true, but also because they provide the moral impulse which alone can lead to that peace, in the true meaning of the word, for which we all long… There is little hope for democracy if the hearts of men and women in democratic societies cannot be touched by a call to something greater than themselves.”
In a normal society, people love their families and their extended families, including their people, also known as their nation. This love has nothing to do with Judeo-Christian values.
As far as “the moral impulse which alone can lead to that peace, in the true meaning of the word, for which we all long”, the East Asians produce societies far more law abiding and peaceful than any seen in the Jewish and Christian worlds.
As long as tens of millions of people such as the Japanese are more decent than the most committed nations of monotheists, I’m not sure how one can argue that God is necessary for ethics (something I’ve believed almost all of my life).
