Further, these micro-organisms are assigned at birth and passed down hereditarily. If you're born with a low God-love count, that number will never change and God will never love you very much, as proven with inarguable scientific accuracy.
Would that not demystify religion for you?
If we choose to believe what Obi-wan states, Midi-chlorians are what connects living beings with the force, and some have a higher concentration than others, I'm not sure why one would find that disturbing or upsetting. There are still so many unanswered questions: How many Midi-chlorians would one need to be force sensitive? Can one's Midi-chlorian's count increase or decrease over time? Is it a purely linear scale, or logarithmic? The Jedi appear to be celibate, so are high Midi-chlorian counts purely a result of genetics, or can they be otherwise manipulated?
But none of this really contradicts what was seen in the earlier movies. We were lead to believe that heredity plays a part. We knew that some individuals were more force-sensitive than others, but that all living things had a connection to it. We knew that through training and discipline, one's connection could become stronger. How does a physical link belie any of that?
Back to your example. I'm not sure I'd agree with the love part of your argument. It's not really analogous to the force, since we don't have a reason to believe that the force "loves" the living. Rather, it may be better thought of as how close one would be to God.
Without getting into any specific religion, we can find many individuals throughout history that have a much stronger connection to God than most others. If it were somehow possible to show a physical attribute that correlates to that closeness, why would it invalidate one's belief or make Him any less mystical? Does it tell us God's motives or will? Does it answer the question of creation? Or the nature of good and evil? Does it define the purpose of man? Do we know if that bond could be strengthened through meditation, other training, or acts of sacrifice? Would it make those with a lower count Godless, or would they just struggle more with their own personal faith and deeds? Would God care any less about them? Would he still listen to their prayers? Could those with average, or below average counts strengthen their connection by communal worship? How does free will fit into the equation - do those with higher counts still retain their ability to chose their own fates, or are their actions tightly governed?
So much would still remain unknown.
Just answering that one single aspect that seems to help explain the interface between God and man wouldn't solve the bigger questions shared by the faithful. So, no, it wouldn't demystify religion, only add a small piece to a very large puzzle.
