Well let the citizen be a good citizen, but it has nothing to do with the science. And making such statements can be counter productive as you make these people feel defensive instead of educating them and helping them understand that science isn't out to destroy their faith. If you make an active effort to do so (thinking that is the problem), you will only push them away. I know, I taught science at a parochial school, and I am no longer employed there for that very reason even though I was sympathetic to many of their views. However, I am a hard liner when it comes to "just let the science speak for itself", and they didn't take too kindly to the that approach. Their having a very wooden/literalist view of the bible, and siding with/politicising and the christian right band wagon is the problem. A theological worldview isn't going to stand in the way of good science and good stewardship of our planet, but a further divide and a culture war will.He shouldn't. But a citizen worried about how large a segment of the US population believes things that have been scientifically falsified, and translates those false beliefs into counterproductive social and political actions, should.
