Academic debate on controversial topics is fine, but those topics need to have a basis in reality. I would not invite a creationist to a debate on campus for the same reason that I would not invite an alchemist, a flat-earther, an astrologer, a psychic, or a Holocaust revisionist. These ideas have no scientific support, and that is why they have all been discarded by credible scholars. Creationism is in the same category.
Instead of spending time on public debates, why aren't members of your institute publishing their ideas in prominent peer-reviewed journals such as Science, Nature, or the Proceedings of the National Academy of Sciences? If you want to be taken seriously by scientists and scholars, this is where you need to publish. Academic publishing is an intellectual free market, where ideas that have credible empirical support are carefully and thoroughly explored. Nothing could possibly be more exciting and electrifying to biology than scientific disproof of evolutionary theory or scientific proof of the existence of a god. That would be Nobel Prize winning work, and it would be eagerly published by any of the prominent mainstream journals.

This is part of Gotelli's response to a request by the Disco Institute for a debate. The biggest problem with the conspiracy/brainwashing/suppression claims is that most scientists love to overturn existing "dogma." They live for it. Show them some credible evidence, and they'll be all over it. Show them bible verses and claims debunked many times over, and, well, you get letters like this one. Everyone really should read the whole thing.
