The element of evolution that the Dover school board found offensive was common descent. There really aren't any competent scientists who disagree with common descent. Even the Discovery Institutes's experts do not question common descent.
A school board cannot override the consensus of science because it finds science inconvenient for religious reasons. And the religious motivation of the school board was established beyond doubt by testimony given under oath.
As far as consensus is concerned, the great majority of scholars disagreed with Galileo about the reality of a heliocentric universe. When “everyone” is an an Aristotlean, a contrarian has few allies. As you admit, the ID people accepted common descent so the judge chose one theory of evolution over another, even though one has the merit of being less offensive to the community than others. At bottom, the judge was simply bowing to convention, the “everyone-I-know—voted— for— McGovern” syndrome.
