When the case for evolution is presented evenhandedly it is astonishly weak and would be less likely to believed. Bureaucrats at NSF and other publicly funded scientific organizations know that if the public were to come to understand how a thinly disguised propaganda operation has been in place since the Scopes trail to prop up a highly speculative scientific theory that there would be a large backlash against these organizations and their public funding. That accounts for the hysterical "let's rally around the flag boys" tone of many of these pronouncements from NSF and other organizations.
