Gee whiz. I can't imagine. Maybe it's because Bono hasn't washed his hair since 1989.
Or maybe that his causes can each be found in the hippie activism playbook; circa 1968. Or perhaps the typical leftist hypocrisy of condemning Americans over the Iraqi war while U2's drummer points out Bono's oozing affection with the other major war player; Tony Blair.
Or perhaps it's U2's wagging their collective finger at all of us during one of their frequent environmental rants. But in typical U2 fashion, Edge is completely deaf to the neighbors and environmentalists who are trying to prevent him from decimating one of the remaining pristine pieces of California landscape in order to build his $44 Million dollar palatial estate.
Or maybe it's just the hippie way Bono shows his loyalty to his Wife and Children.
