If you listen to some of Bob's other debates, I think you'll find that guests are not treated with disrespect.
It's not a matter of disrespect. It is the format. A radio program is a very poor format for discussing fossil morphology, as one example. Since many of your "evolutionary gems" disputes the transitional nature of fossils which necessarily requires a dissection of the fossils themselves it would seem a bit ackward to just talk about them without the audience being able to see what you are talking about.
Audio only is a very poor way to discuss these topics. Even genetics would be nearly impossible to discuss. For example, I would want to discuss ERV's, and to do so I would need to use visuals showing how LTR's flank the viral genes, how the retrovirus inserts, examples of genomic distribution of retroviral insertion, etc.
Also, staged debates are a very poor way to discuss this topic anyway. For any challenge there needs to be time for a well researched response. Are you really going to make you audience wait for 30 minutes while I do a Pubmed search and at least read a couple papers cogent to the points being made?
This is why forums like these are a much better format for these discussions. Perhaps you could pick one of your "gems" and start a topic (either here or at your site with the agreement that you will let us post at your site). After a couple of weeks you could refer your listeners to the online debate and judge things for themselves.
