The atheist community is deeply divided about religious fundamentalism and creationism, but not about whether such preposterous claims have any validity. They disagree on whether scientists should debate fundamentalists about the "science" of the Bible. I think both sides have reasonable arguments in the debate on whether to debate.
Here are arguments against debating: What's to debate? Evolution is--true! That a man named Noah put pairs of all species from a 6000-year-old earth in an ark he built when he was 600 years old is--false! Sharing a stage with creationists just lends them credibility. In any case, evidence will eventually win. Debates are often more about oratory skill than evidence. Preachers and pseudoscientists usually have more debating experience and skills than do scientists. Should we also debate Holocaust deniers or members of the Flat-Earth Society?
Here are arguments for debating: If scientists don't defend scientific theories, we will lose the battle of public opinion. Many fundamentalists have heard only the preacher's side and a debate might spark illumination for some who listen to a scientific theory explained by a real scientist.
