Why Aren't Evangelicals the Ones Meeting Us Halfway?

I know is this a bit off topic for the week (to put it mildly), but I was struck by the newsweek article on the Evanglical Identity Crisis, in particular:

At Willow Creek's annual meeting last summer, the highlight was a video of Hybels and Bono hashing over the fate of the world. Bono quoted Scripture (Luke, chapter 4); the crowd wept. Cally Parkinson, who runs the Willow Creek media-relations department, was there. As she was leaving, she overheard one pastor say to another, "I went in there wondering if Bono was a Christian, and I came out wondering if I was."

There has been much hand-wringing about how the progressives should try to find common ground with the "Evangelicals". Well, I'm going to turn the question around, why aren't they the ones meeting us halfway? The causes embraced by both Bono and (some) Evangelical Right are the same causes already embraced by the secular liberals. Why should we be the ones doing all the "understanding" and "outreach"?
