The reason scientists are wary of religionists doing evolution is not just that they bring in design arguments, that is par for the course, but that they mix two modes, science and religion:
they do science on evolution (if they are not typical creationists, but groups like the Discovery Institute),up to a point, but then they hold in reserve issues assumed by faith, i.e. the legacy of Old Testament history. The two things can never combine properly and that is that.
Groups like Templeton need to first debrief their own assumptions abut ‘design in history’ and simply set aside the Old Testament as a lost cause that can’t be taken on faith.
The issue of design creates panic in darwinists. That is ridiculous. Design arguments can be claimed, but since the proof is elusive is not metaphysical, it is hard to see why biologists are so paranoid.
The real reason is obvious: the theory of natural selection is even more metaphysical that that of the ID group. They have to maintain the rigid belief on faith to keep the expose at bay.
