Argument Against Liberal Theism: http://www.ebonmusings.org/atheism/godislove.html

If you really want 'proofs' against the exitence of a God (or Gods), then these are the best you can get. Of course, even these are not conclusive in proving that any God couldn't exist. Also, I do not expect you to read all of them, so here are summaries:

1) An omnipotent, omniscient, omnibenevolent God could not exist because of the evil in this world. Theists' attempts to defeat this logic are inadequate.
2) Since God does not reveal Himself to us, we must conclude that a God who is interested in human affairs does not exist.
3) If God is how liberal theists traditionally define Him, there is no point in believing in Him.

Of course, they go into much greater depth than that, but you get the point.

(I must admit that I have never looked at this site and as I post this, I as of now have not looked at this site. I will do this at a later time because I have something else occupying my time at this time, but I will look at it later when the thing occupying my time is no longer occupying my time. I recognize the possibility of this website not being a good website, but if it turns out to be, then you should probably point that out.)
