I enjoyed your essay. :) 

I consider non-duality as an incomplete concept - of the Infinite undivided and unable to know itself.  I consider it as extreme positive, opposed to extreme negative  - identification with a separated ego-mind. Ego-mind doesn't exist apart from the Creation, but I exist because I've read what you just wrote there. It is actually the only thing that you can be sure of - that you exist. 

Non-duality also seems a little plagued by exclusive/pure-human perspective, because the Universe is very much inclusive and integrative, so I would be more willing to state that You exist and You don't exist - simultaneously on many different levels.

Other than that, ego-disidentification is something that humanity, as a collective, is more aware of from moment to moment, so keep up a good work shining your light on the subject. :)

One I can state for sure - our Truth lies beyond even the concept of existing and non-existing. It is ineffable.

Very good job with the post. Upvoted and followed.
Much love, my Friend. :)
