I can say that agnosticism is a position ON knowledge. That's what the word means. "a" means without and "gnostic" means knowledge. Without knowledge, just like a-theist means without god. I am an agnostic atheist. That means I don't know whether or not any gods exist and I don't believe any gods exist. What you can't do is say "I don't know" when I ask you what you believe. Do you understand. When someone says "Do you believe in God," the response "I don't know." Means you don't know what you believe which is stupid. No one asked you if you know God exists.
