From your response it's now becoming clear why we have different stances on this subject. You are blurring the line between belief systems and religion to the point where you feel that any belief system is in itself a religion; it is not. Ethics, morals and behaviours can all be shaped by a multitude of beliefs which have no basis in religion. This is why you feel my definition of religion is too narrow, and why I feel yours is too broad.
To highlight this, here's an example:
Is it true that religion is a belief system? Yes.
Is it also true that a political outlook is a belief system? Yes.
Is a political outlook a religion? By your definition, yes. By my definition, no.
Thank you for stating the religion you follow and the application of why you think you're religious against my definition of religion. What is apparent from your first point is that you don't actually follow a defined set of rules from your God, as you have no Holy text or scripture to follow. To constitute being a religion you require some kind of physical embodiment of your God's rules, as without this you are simply following your own path in much the same way as I do.
You can probably guess by now that I would have to answer no to your question on whether I would say you have all the defining elements to be in a religion, or that you're religious. Ethical monotheism in itself is a belief system, not a religion for the reason I outlined in my above paragraph.
I have no objections to your term belief system.
Ultimately, however, I take the position that your distinction between religious, political, and philosophical, belief systems is arbitrary.
All of these belief systems are logical systems that can be traced back to at least one and sometimes multiple faith based axioms. The ardent Communist may hold of the Communist Manifesto and say true. The religious man may hold up his holy text and say true. The Nihilist Atheist may yell his belief that the universe is utterly random, he also holds onto his belief and say's true.
All humans follow faith based belief systems. Each individuals system is slightly different and they vary in their degrees of coherence.
Some faith based belief systems are more articulated then others with common principles that are written down and widely shared. Other individuals hold their core principles internally or follow them subconsciously. What is important is not whether the faith is written down that is just a reflection of how commonly shared the belief is. What is important is that individuals are aware of their faith and explore its logical consequences.
As far as I can tell our only real area of disagreement is whether individuals who follow a faith based belief system should be categorized as religious.
As the term religious is itself an arbitrary the various online dictionaries for example have 4-7 different definitions for this term. Exploring that dispute is not likely to be particularly productive.
You might find my recent post in the Health and Religion thread interesting. I was asked why I believed in God. This was my answer.
Why Do I Believe In God?.
