:I'm new, so my thoughts aren't as valuable as those of the folks who worked so hard to hammer the lead into its present shapeand by the way, I want to thank those folks, who gave me a real education in how people with different points of view can work together productively to arrive at a consensus.  I was impressed by the demonstration, and it's too bad that things went wrong just after that, because it did seem like significant progress was being made.  But having said that, I do have to agree that "metaphysical" is problematic.   I like your construction (except that the second sentence is a fragment).  Is it even necessary to have an adjective there; couldn't it just say "ideas extracted from quantum physics to rationalize or support certain new-age beliefs"?
