I still dont' see how the Midichlorians make the Force any less of a spiritual entity. They simply give a bliological explanation for why some can weild said entity as a source of power and why others cannot.

It's like if one man God gave the abilit to speak very well, and other man did not have this ability. Not having the ability wouldn't make the second man evil or less able to have faith in God, and if anything it would put MORE responsiblity on the man with the ability to speak.

And said man could use ability to speak for good, like say, Mark Twain or Billy Graham, or he could use the ability for evil, like Adolph Hitler.

See the parallel?
