I don’t believe politics is based on logic or the rational knowledge developed from science.
I believe the same is true for society.
I wholeheartedly agree -- and I'm not entirely convinced that things would be that much better if it were otherwise. Life provides many interesting challenges for those who love puzzles, but finding (or thinking you have found) the solution to some puzzle doesn't automatically guarantee that you will experience a higher quality of life as a result. Social structures need to take into account the way humans tend to
feel about certain things, regardless of whether those feelings are firmly grounded in logic. Belief systems like Christianity have this down to a science (so to speak).
I believe that the best way to avoid clearly untrue beliefs from adversely affecting a society too much is through the dissemination of knowledge.
I agree with that as well; I just don't think public debates between scientists and creationists are an effective means of achieving that.
True believers are waging an ideological war with any science that disagrees with their religion. They are very serious about this.
That's true, but it's also true that this has been the case for some centuries, and they have been steadily losing ground all along.
They are working very hard to present their view to the greater public as being the correct and true belief.
And in doing so, they rely not only on outright lies, but appeals to emotion. This is an effective strategy, and, as long as the quality of the discourse is dictated by the nature of the venue, a strategy which can only be countered by responding in kind. It's hard to argue effectively from logic and reason if you're appearing as a guest on the Jerry Springer show.
Correct me if I am wrong, but I could swear I have heard several stories about creationists making potential political ground towards having Creationism taught in public school along with Evolution.
There have been a number of threads on it here. I believe
Wikipedia's account of the history of the struggle is fairly accurate, and reviewing that, you'll see that creationists' success at promoting their agenda has been limited and fleeting.
