Mark Nelson has been exceedingly polite on Twitter to Dr. Paul Dorfman.
Eventually Paul did agree to participate in a televised debate.
The original conversation can be found here: https://www.aljazeera.com/program/inside-story/2023/4/15/why-has-germany-shut-down-its-nuclear-plants
Original was 27 minutes. This is 9 minutes.
There were 3 participants originally, but I think it moves much faster when reduced to just these 2 participants.
