Much of what passes for debate hereabouts falls into a few categories. There are considered judgements based on long experience, personal opinion with the usual smattering of prejudices all humans are prone to and simple caprice - right now in this mood I think x.

The danger is mixing a, expertise, and assuming every other observation we make falls under the same category. I fail to see any objective method for deciding whether people should join in or not that is arrived at beyond capriciousness.

Arguments usually begin from a sense of humour bypass, not a misunderstanding of the available facts.
