But the following is among the reasons I get concerned about his, or anyone's, overstepping science in an effort to affect social policy.
I understand, but I think Dawkins and other biologists are still best known for reacting to those who overstep
social fields into
science, specifically those who deny evolutionary biology and other firmly established scientific principles on religious grounds. He's entirely right to emphasize that evolution isn't any less true just because some misguided people misused it to rationalize all sorts of odious behavior. Science is
descriptive, not
proscriptive.
As a biologist, Dawkins is ideally situated to refute creationism. But why should he limit himself to that when he sees religion causing many other kinds of nonconsensual harm? There are all sorts of false but firmly unshakeable beliefs that prompt people to do horrible things to each other and we don't seem to have a problem labeling them as "delusional" unless they involve religion. Why should it be exempt?
Dawkins and other outspoken atheists continually cite the harm they perceive religion causes to others, and I don't think they need to apologize for this. Governments and laws exist (or are supposed to exist) precisely to protect people from harming each other, and as citizens in liberal democracies we're supposed to continually participate in improving those laws.
But if Dawkins were to advocate action against people solely for their personal religious beliefs that harm no one else, he would cross the line just as the bluenoses do when they tell consenting adults what they can't do within the privacy of their own bedrooms. Now I might have missed something, but I've never seen him do this.
Many people falsely portray Dawkins and other atheists as out to deny their freedom of religion because they're simply in denial that their religiously-motivated actions do in fact harm others. Worse, some feel that their religions
entitle them to cause such harm. They just don't seem to understand that while religious freedom is a basic principle of our country, it does not include the freedom to harm others or to use the machinery of the state to coerce others to follow their personal views.
