I'd agree with this wholeheartedly. In particular, we (meaning all of us) need to learn how to have technical arguments without it becoming personal.
Would this be a good opportunity to draw a line under old differences? I don't expect us to magically agree on the right way forward, nor would that necessarily be healthy, but we can at least start to be nice about it.
(Taking this a step further, I'd be interested to hear what others think about the codes of conduct which are used in communities like Groklaw and Ubuntu. Not something you can enforce in the newsgroups, obviously, but may be of some benefit elsewhere.)
