I think the key difference among the many differences is core values. Most on our side have a set of relatively unchanging core beliefs, the Greco-Roman and Judeo-Christian heritage. Our values are frequently formed around Biblical teaching. These values have been developed over thousands of years and passed down to each succeeding generation. However, If you place your values on the trending socio-political philosophies you have no core because those philosophies and the "values" they present are constantly changing. This is the heritage of the Enlightenment. It is called being a Progressive.
