Scientists are more than willing to debate in public- that's what scientific journals are for.
Or are you talking about a debate in front of a live audience, where the creationists/ID'ers throw out 50 points in three minutes and then proclaim victory when the scientist can't responde to that smorgasboard in the alloted time?
Cute, but they won't even allow for that in most cases.
Avoid the ad hominem and straw man attacks.
A Scientific journal would, no doubt, forbid any publishing by a respected creationist...since he cannot be a scientist and a creationist simultaneously.
Any evidence to support that scientific journals have allowed such publication?
ID proponents have had to fight through the same.
