How the moral standards can be distinguished from non moral standards?

Answer 1

Public moral is usually imposed by society and its' values...In Nazi Germany it was merely moral to abash and terrorize Jewish citizens, for example...There were even the so called "Jewish laws", invented by the "reichsmarshall" Herman Goring which designated all the Jewish as lesser citizens with lesser rights, concentration camps were being established for people with any democratic perceptions of society, the regime systematically annihilated mentally handicapped and finally anyone who was brave enough to speak his own opinion in public...In democracy, there are none written rules as far as moral standing is involved, except the obvious, which is written in a constitution...There are of course unwritten rules widely accepted by all the civilized societies, like: respect for the elderly, the sick, the feeble...In practice however, they depend more or less on our own perception of the moral, so basically one could say: we invented morale and it is our responsibility to act according to it !

Answer 2

If I understand your question: a moral standard ought to stand the test of ethical reciprocity, i.e. the Golden Rule.

Of course, the GR is not always straightforward to apply and there is always the temptation to rationalize and twist it.

Answer 3

Moral standards are pure, clean, forgiving, merciful, kind, and non destructive. Anything less is non moral.
