- RO- Religious and Observant - This is the elite and rare group of people across all the different denominations, Chassidish, Yeshivish, Yeki, Conservative, Hungarian, Polish, Lutvak etc... who observe the Mitzvos - at least as far as one can see or professes to be bound by halacha - and is searching to understand the purpose of man in this world as it relates to his Creator.
- ONR - Observant but not Religious - Most of what one calls Frum Jews the world over - they keep all the mitzvos to the utmost detail, follow blindly their leaders, afraid to think, ask or answer. They do it all because they want to make sure that God does not punish them. These people are basically superstitious simple good people and have always been the mainstay of Judaism. Without them we would not be here. They include the leaders and those crowned by the same temimim as "Gedolim". Most of the Yeshivaleit, kolel yungeleit and baale batim, talmidei chachomim and amei hoaretz are included in this group.
- RNO- Religious but not Observant - That includes a lot of the intellectuals, people who struggle with the existential and theological issues but do that without observing the Mitzvos whether intentionally or not . They include all branches of Judaism, Islam Christianity and probably many other religions. ( I am not well informed in comparative religion so I cannot say this with authority). Gershon Scholem, Spinoza, Kant, Aquinas to name a few would fit in this category.
- NRNO- Non religious and non observant - The majority of mankind who are either superstitious, uninterested or unsympathetic to any questions that go beyond their day to day existence. They span across all cultures and religions.
I am sure not all will agree and i am willing to entretain suggestions that make sense, but I believe this to be a sensible and realistic proposal. So how about all of us using it so that we know what we are talking about.
