What he meant was that explaining the Force removes some of the mystery about it. All we knew was that it was an energy field and that, somehow, a chosen few could hear it. Now we know that it's in our blood and know exactly why we have the chosen. It's like the difference between believing in the existence of God, and meeting him. Plus, if it's been proven that those with more midiclorians are Force sensitive, why are there those like Han who don't believe when there's documented scientific proof to the contrary?
As for Palpatine creating Anakin, I'm still undecided on that. It just seems like it creates more questions than answers.
