Well, let’s say for the sake of the argument that he is wrong.
A lot of scientists propose theories that turn out to be wrong. As long as they don’t fake or fudge their evidence, what’s so bad about that? If he can be proved wrong, then presumably it weakens the case for ID and indirectly helps to advance the science of astromy by eliminating one possible theory.
What is simply intolerable in this and similar cases is that he is being kicked out of his job like a criminal for proposing a politically incorrect thesis. That isn’t the way science is supposed to work. Various people propose various theories, and the better theories work their way to the top and the others are discarded. Or, alternatively, the book is simply ignored.
There is a kind of hysterical bigotry and intolerance on the part of the anti-ID people that is truly frightening, because it suggests that our scientific establishment has really gone onto ideological steroids and is unwilling to adhere to the normal rules of scientific discourse. Instead they turn to bullying, persecution, and activist judges to enforce their beliefs, and will tolerate no questions whatever of their views.
You do know the difference, in science, between a hunch, a guess, a hypothesis and a theory, don't you?
