The Need for Moderation
I think the issue goes beyond the practical effect of attacks on religion on the successful teaching of evolution as a scientific theory (which, it should not need to be said, means it has been proven beyond reasonable doubt). Religion at large is being smeared because scientists, of all people, are allowing themselves to make a generalization the basis of a very limited sample of information.
This is religious bigotry in a weird kind of inverted form. Scientists are turning their hatred for the religion of some into rejection of all religion, even ones they know nothing about. It is furthermore the height of irrationality to reject religion for not perfectly mirroring the findings of science. Religious myth does not attempt to explain the world as science does. It is attempting to express various understandings about our place in the cosmos. These expressions are epistemologically the same as literature. Literature is made up of works of fiction and poetry. Neither conveys truth as science does, in propositions that can be tested with direct observation and experimentation. A book does not have to be literally true for it to convey truth to the reader. The same is true of poetry. Religious ritual has more in common with theater and dance than science. A religious ritual is not trying to express some proposition that must be tested with logic and observation. It is creating an experience for the person or people taking part in it.
If science invalidates religion, it must also invalidate all fiction, poetry, music, dance, and art. Please speak out about this whenever you hear someone argue that science has replaced or ought to replace religion.
