I think my original proposal of just two “rooms” was too crude to capture what I was driving at. I think the objections above from Nathan and Neil could be accommodated within my general idea, thus:
Section 1: Discussions for People Interested in Debating the Truth, Usefulness, or Goodness of Christianity, or Theism in General, or Religion in General. (Debates and quarrels about the Bible, about the existence of non-existence of God, about whether religious people are on the whole any more moral or socially co-operative than non-religious people, etc., would take place here.)
Section 2: Discussions for People Not Interested in the Discussions of Section 1.
Section 2 would be divided into any number of “Rooms” which might include:
Room A. Proposals Regarding the Synthesis of “Good Science” with Various Religious or Theological Positions. (No subscription to Christian faith required, only openness to the questions as valid intellectual questions, and a promise not to try to turn the discussions into Section 1 Discussions.) In Room A, proposals such as GAE would be discussed, and also other proposals, e.g., those of Robert Russell, Hugh Ross, Alvin Plantinga, William Lane Craig, etc.
Room B. Discussions of the Relationship between Intelligent Design and Evolutionary Thought. (Deliberately avoiding personal and political speculations about the social, political, or other motivations of ID proponents and evolution defenders, and concentrating on the scientific data, philosophy of science issues, method issues, etc.)
Room C. Discussions of Various Scientific Subjects Impinging upon Origins Questions, Evolution, etc. (These would not need to have any theological focus at all, and usually wouldn’t discuss theology except in passing; they would be more like an information exchange regarding the latest findings and notions scientists have put forward regarding origins or the sciences connected with origins.)
Room D. Discussions about Science in Modern Society. (These could include discussions about anti-science attitudes in culture, where they come from, how they can be constructively addressed; discussions about the place of scientific expertise in the political ordering of modern democratic societies; discussions about the problems with Scientism; etc. People who wanted to complain that Bush or Trump or Republicans etc. were anti-science, or that science research should receive more generous funding, or that Science should not be privileged as the only or even the most important road to Truth, would post their ideas here.)
Room E. Ethical Issues Potentially Connected with Evolution. This could include discussions of real or alleged historical connections of Darwinian ideas with eugenics, with Nazi ideology, etc.; it could also include questions of medical ethics that might arise from an evolutionary perspective, or questions whether close evolutionary relatives of man such as chimpanzees should have legal rights, etc.
I have given only a few examples of the “Rooms” that would be possible. But I think they are enough to show that atheists, agnostics, etc. would be able to participate in discussions in any of the Rooms, subject to their willingness to respect the purpose of discussions in that Room. If ever they found a particular Room too confining, they could go and converse in one of the other Rooms where their specific concerns could be aired more freely and fully.
