[quote=Magic Magnum]As for the Agnostic bit.
Agnostic simply means unknowing. Although culturally it's used to define atheists open to the idea of a God (or outright believe a god like entity) it is in fact a false usage of the word.
In practice, Agnostic's can also be religious, as long as they admit to not knowing something. For example.

Fundamental Religious: My God is true, and there is nothing you can say or show to change it!
Agnostic Religious: I believe in God, but I do not know for sure. 
Agnostic Atheist: I do not believe in God, but I cannot say for sure there is a God or not.
Fundamental Atheist: There is no God, and there is nothing you can say or show to change it![/quote]

I know the meaning of the word agnostic, but I guess I can't fault you for feeling it necessary to explain. Lots of people seem not to understand the meaning of the term, because I guess it's hard to find the definition of a word even on the internet. :hehe

Also, the four quadrant model of beliefs is typically stated with the paired antonyms of theist/atheist and gnostic/agnostic. Substituting theist for religious is misleading because atheists can be religious too; for example, those "there absolutely is not god" atheists and religions like Buddhism that lack deities. Substituting gnostic for fundamental is misleading because fundamentalism is a particular brand of gnosticism and one can hold gnostic belief without being fundamentalist; for example, Christians who absolutely believe in the existence of their deity but do not think the Bible is the literally true word of that entity hold gnostic belief in said deity but are not fundamentalists.
