I was so impressed with Sam Harris and Jordan Peterson. Please note how even though they seriously challenged each other's core assumptions and beliefs a whole bunch of times, observe how they utterly kept their cool at all times, and found many points to agree over. Near the end of the discussion, they even complimented each other's strengths.
If you could have your way and have certain living Theravada Senior monks engage in gentlemanly, frank discussion and co-operative exploration over various controversies and sticking points in Buddhism (in a similar way demonstrated here), who would talk to whom? If you could have the above discussion happen with living Buddhist monks, whom would you put into the positions of Sam Harris and Jordan Peterson, as they explore where "truth" lies, in the context of Buddhism?
BTW: If two monks simply don't get along for personality reasons, that's not really the topic of a good discussion. But then again, if it's just two harmonious monks simply "gladhanding", that might not be all that "juicy"; there needs to be some significantly differing perspectives, like I would say Harris and Peterson had. So almost like a debate, but not quite, in the sense that it remains constructive and positive. The discussion should be over some sort of Buddhist doctrine or discipline, where they take up opposing, or at least significantly differing views.
No doubt Ajahn Brahm will get mentioned (what with the whole Bhikkhuni thing), but can you think of others? Let's not get stuck on that one issue, please. I would like to disarm that bomb before it explodes.
