religion

Separation of Church and State. The line is constantly blurred and forever challenged in the U.S.

Some nations are founded on religion. The US is not a religious state.

In Israel, the Jewish state, the nation was founded as a safe-harbor for Jews after the holocaust. Religious disparity, even within the ranks of Jews is a source of infighting and in some cases extreme violence in Israel today. The first problem is having a "minister in charge of religious affairs." This reflects the core belief that religion and matters involving religious beliefs are a function of the government. The second problem is when there is only one accepted religion in the state. This creates religious castes at best and threatened sub groups at worst. The surrounding Islamic-ruled nations are an extreme example of such religious oppression.  Alternate religious groups are persecuted and women live subservient, suppressed lives in the religious lands. People are ruled under ancient laws.  While their society is more modern, Israel cannot see it is just another tree in the forest.  It's Jewish citizens enjoy greater rights and privileges based on their religion.

Secular countries have social, economic, ethnic and religious distinctions as well. The difference is a ruling social order is not in permanent control of government. There is a constant tug of war for control and certainly the wealthy have their influence as well as religious groups and other lobbyists affecting politics. If any one group were to seize absolute control, oppression would result and social castes would form.

Religion and spirituality are often not the same. At its best, religion can lead to spiritual life and for that reason I respect most religions, but only when they inspire men to be their best. Right now, we don't see enough of that.
