How we, too often, do Biblical study and interpretation

From an article in First Things on the Green Bible:

The Green Bible presents us with a curious kind of natural theology: We start with things we know to be true from trusted sources—Al Gore, perhaps?—and then we turn to Scripture to measure it against those preexisting and reliable authorities. And what a relief to discover that God is green. Because we already know that it's good to be green—what we didn't know is whether God measures up to that standard. Alan Jacobs, "Blessed are the Green of Heart," First Things, May, 2009.

I haven't seen the Green Bible. I don't know whether Jacobs' criticism is fair or not. (He indicates, in the article, that he is doing his part to take care of the environment himself, and there is a comment to the article that he was not being fair.) I do know myself, and how I sometimes act. How often do I do that sort of Biblical study and interpretation? Doing it in reverse, that is -- starting out with a preconceived view and searching the Bible until I find justification for it?

God help me.
