You seem to view Agnosticism as merely a transitory step. I see it as more than transitory -- as a state in itself - a lack of ability to have faith.
I accept something when there is evidence to support it's existence. To that end, I don't believe in Norse mythology, or Hindu mythology or Greek mythology or African Juju. When the Jehovah's Witnesses show up at my door, I don't follow them down to Kingdom Hall. I don't think that disease is cause by witches or evil spirits. There is a very very long list of things I don't believe based on a lack of evidence.
