Can an essentialist really understand the view of an anti-essentialist? If I live in, and believe there is only "is" or "is not", then how can I begin to understand someone who tells me I am missing the point?
This isn't simple. For instance, Bhāviveka implies (the Tibetans say he argues) that Nagarjuna accepts that the structures of argument (classical logic) exist in a shared communal space: That both essentialists and non-essentialists share a common ground in classical logic.
Candrakīrti thoroughly disputes both Bhāviveka's interpretation of Nagarjuna as well as his (Bhāviveka's) critique of Buddhapalita. Instead, Candrakīrti argues strongly for prasaṅga (reductio) as the sole structure available to the Madhyamika (ie, follower of Nagarjuna).
Nagarjuna, according to Candrakirti's position (and that held by most modern Madyhamikas) would neither call himself a dualist nor a non-dualist, as it doesn't mean anything to him to do so.
I believe that you and I may be seeing things not so differently though. For instance, I would agree with you that Nagarjuna rejects all "extreme metaphysical positions" - but what we are faced with is "what is included in 'extreme'"?
In your essay, you also say "Nagarjuna painstakingly proves that there are no contradictions in Buddhist philosophy." – regardless of our differences, I am sure you must agree that this is a conflation of a large order: He recognises his primary opponents as being Buddhist philosophers. (Read Jay Garfield's translation and commentaries on this - most sources are in Tibetan, but there are some great translations available now).
What he argues is that any system (Buddhist or non-Buddhist) that asserts an objective (or inherent, or essential, or self-standing) 'truth' is false. He uses the language of the opponent to demonstrate prasanga - reductio - of the opponents own position.
So, your primary source for Nagarjuna is Khenpo Tsultrim Gyamtso, himself an eminent scholar. He follows the views of Mipham - another scholar - who invested a lot of his writing life objecting to Tsongkhapa - yet another eminent scholar.
I'm really not able to write as well as Garfield on this matter but, even though he argues for Tsongkhapa, it may give you some insight into the depth of thought that goes into the question.
Honestly, when it comes to the MMK, I recommend that you study all the major scholars, regardless of school.
Anyway, when you say to me that you consider my view to be a most damaging misunderstanding it makes me think that maybe you are concerned that I have ended up in a nihilist position, where nothing is real, and that lies are truths - some sort of extreme of relativism? But I have not, and I do not. Instead, I recognise that causality entails essencelessness, and that essencelessness entails causality. Every action has a consequence, without fail.
