After some consideration I'm siding with nwr on this one. However, both parties puzzled me.
It started with nwr simply commenting he was skeptical of the BB. Percy asking to discuss it further, and nwr agreeing. Nwr made it clear he was not trying to refute BB, just that the evidence he had seen hadn't been enough to convince him.
Percy continued to debate nwr as if he were trying to refute the BB, and it went around for a while with nwr trying to explain this wasn't the case. Eventually Percy concluded that nwr was letting his ignorance shine through.
I'm puzzled as to why nwr thought it was a good to idea to put his opinion forward in a debate board without the opinion being...debated.
On reflection though, Percy was less civil than he could have been and it discoloured the flavour of debate. If his purpose was to show that two evolutionists debate the same as an evolutionist versus a creationist - then all he really achieved was showing that creationists get given a hard time around here.
If Percy succeeds in making this debate style the norm, I'd be very disappointed. We all like to see people that make grand declarations about how their opinion of science is Truth get taken down a notch and shown to be the arrogant ignoramuses they are. However, I don't think I want to be part of a culture where tentative skepticism is met with criticism and accusations of ignorance.
If a creationist says 'I'm not convinced by the evidence of macroevolution' then I'd rather see a discussion along the lines of 'Let's look at the evidence and discuss what you think of it.'
I don't think it warranted suspension personally. Though I suppose it shows that even the board's administrator can be rebuked by other mods - so that equivalence thing is working. Still - I think the best thing for nwr to have done is called an end to his discussion with Percy and concentrated on the discussions with the cosmologists.
Not a perfect solution, but I don't think suspension was quite necessary.
