How can we determine what is morally right? The answer to this question the most important question human beings need to answer is a major difference between Left and Right.
For conservatives, the answer is, and has always been, that there are moral truths objective moral standards to which every person is accountable. In America, this has meant accountability to the Creator, the G-d of the Bible, and to Judeo-Christian values.
For the Left, the answer has always been meaning since Karl Marx, the father of Leftism that there is no transcendent source of morality.
On the contrary, as Marx wrote, Man is G-d, and therefore each human being is the author of his or her own moral standards.
There are, of course, both religious leftists and secular conservatives, but the secular-religious difference explains many of the fundamental differences between Right and Left.
As a rule, leftists fear and have contempt for people who base their values on a transcendent source such as religion and the Bible. Such people, in the Lefts view, cant think for themselves they need a G-d and a religion to tell them whats right and wrong. Leftists contrast these conservatives with themselves, people who think issues through and do not need G-d or religion.
