But to refuse to debate is to give out the message that somehow we are afraid of being shown to be wrong. After all, don't many of us take the fact that psychics etc refuse to take the JREF prize test as evidence that their claims are false? Does our refusing to debate creationist lunatics give the impression that we are afraid of being shown to be wrong?
If these people offered a valid $1million prize for a refutation of their points, it would last about five minutes before being claimed. The strength of the JREF challenge is "Why would anyone pass up $1million?" With these debates, what does the evolutionist stand to gain? Of course, there are plenty of people offering "prizes" that are worded so that no one can claim them, as in "Prove evolution to my satisfaction and I'll give you $X" when it's clear that this person will never accept evolutionary theory, no matter how much evidence is presented. I've even seen people trying to use the JREF challenge as support: "Evolution violates basic laws of science, there's a prize for anyone who can prove the existence of something which violates basic laws of science, the prize hasn't been claimed, so evolution is false".
As for the creationist throwing out so much stuff that the evolutionist can't respond to it, a counter tactic would be for the evolutionist to write down every point on a separate pice of papper, and arrange them on a roulette wheel. Then he announces "Absolutely none of these points have any validity. I'm going to choose one at random, and I'm sure that I'll come up with one that's easily refuted, because they ALL are easily refuted." Then do so.
Another strategy might be to take countermeasures against the creationist using persuasive, but invalid, arguments. Creationists like to use lawyer tricks, without the safeguards against those tricks. What if a debate were run according to the laws of evidence? Get an actual judge to moderate, and either debater can interrupt with objections at any time.
"Raw energy cannot generate the specified complex information in living things."
"Objection, begging the question."
"Sustained"
Something else that evolutionists should do is to get the creationist to formulate a specific thesis that can be argued objectively. Something like "Creationism makes more sense than evolution" is not going to lead to productive debate, because it is a completely subjective statement, and it will invite completely subjective arguments.
Finally, if one wishes to refuse a debate, one might do so in a way that makes it clear that one is not opposed to debate, but to the attempt by the creationist to arrange things in their favor. For instance, say "I'd be happy to have such and such a debate" and when they say "That's not the debate we want" and try to claim that the evolutionists are refusing to debate, one can respond "No, we are quite willing to debate. It is the creationists who are refusing to accept our terms".
