Sea Breeze--You just made up your entire post about the Jews. Like my grandmother used to say, the world is filled with unmarried marriage counselors.
"Orthodox" Jews only came into existence in the modern era once the Reform Jewish movement began in 1810. They did not exist before.
They are considered "Orthodox" only in the West, in the United States of America, for the most part due to the fact that Jews in the USA who did not join the Reform movement were labeled "Orthodox" by members in the Reform group who used to make fun of them.
This group further divided among themselves according to how they viewed Jewish tradition and application of Jewish law, the first significant division forming the Conservative Movement (meaning the group in the middle or "in between," the "so-called" Orthodox and the Reform). The movement is called "Masorti" in the UK.
A minor but significant branch would later influence all of modern Judaism via its founder, a small denomination known as Reconstructionism. After that a significant number of practicing atheist and agnostic Jews in various synagogues would begin a movement known as Secular Humanistic Judaism in 1966.
"Orthodox" Jews are actually called Haredi or simply "religious" Jews and are themselves divided into several movements, such as the Chasidim and the Modernist.
All of these are actually part of just one group of the Jewish culture, namely the Ashkenazi, the lighter skinned Jews of Eastern Europe origin. I am Sephardic, the darker skinned type of Middle Eastern origin, and we have no such denominational divisions.
Ashkenazi make up about 80% of the Jewish population in the US, but not in Israel where the numbers are equal. In the world, the Ashkenazi are outnumbered as along with other groups like the Mizrahi Jews, Ashkenazi are actually not as significant as they seem in the West.
In Israel, Jews are called merely "religious" or "secular," not "Orthodox" or otherwise.
