I know that many people are put off by this kind of an aggressive attack on illogic, superstition, and religion, but of course I would disagree with them.
In fact if we look around we can see numerous examples of people in positions of power making important choices about education, women's rights, and basic human freedoms based on a Biblical mind view that is anti-intellectual and ultimately damaging to the future progress of our people.
For quite a long time most scientists believed that Creationism and its ilk would simply die out as more people became educated, and they resisted the distasteful task of getting into the trenches and battling the ignorance behind it. Instead what happened is that it spread and has become pervasive and even entrenched in certain parts of the country making the task of enlightening our fellow Americans virtually impossible.
So I applaud the efforts of aggressive scientists like Richard Dawkins and Lawrence Krauss to take this issue head on. Ultimately I think our country will benefit from their courage.
