That's because he writes things like Must we always cater to the faithful when teaching science?.
As long as I have been a scientist, I have lived with my colleagues’ view that one cannot promote the acceptance of evolution in this country without catering to the faithful. This comes from the idea that many religious people who would otherwise accept evolution won’t do so if they think it undermines their faith, promoting atheism or immoral behavior. Thus various organizations promoting the teaching of evolution, including the National Academy of Sciences and the National Center for Science Education, have published booklets or websites that explicitly say that faith and science are compatible. In other words, that is their official position. The view of many other scientists that faith and science (or reason) are incompatible is ignored or disparaged. As evidence for the compatibility, the most frequent reason cited is that many scientists are religious and many of the faithful accept evolution. While this proves compatibility in the trivial sense, it doesn’t show, as I’ve pointed out elsewhere, that the two views are philosophically compatible.I agree. Organizations like NCSE, AAAS, and the National Academies should just talk about science. As soon as they start to say that science and religion are compatible they are misrepresenting a huge number of scientists and stepping outside their mandates.
Because of this, I think that organizations promoting the teaching of evolution should do that, and do that alone. Leave religion and its compatibility with faith to the theologians. That’s not our job. Our job is to show that evolution is true and creationism and ID aren’t. End of story.
