I'm not totally convinced that a 'pile-on' is a good indicator of anything other than the make-up of the forum.
When someone is wrong about something, whatever their position, particularly when they are misinterpreting or misreperesenting scientific research it is incumbent on us to correct their mistakes, if we truly want a worthwhile scientific debate of the issues.
I think that there is no more tolerance on this site for mistakes from the evo than the creo camp. The problem is that there are many more in the evo camp capable of seeing the mistakes which frequently crop up in a typical creationist argument than there are who would be capable of catching out Mammuthus, for instance, in an error regarding some abstruse detail of endogenous retroviral phylogenetics (not that I am suggesting Mammuthus makes such mistakes, its only an example).
Maybe we need to start a rota for people to adopt-a-creationist and try and avoid pile-ons .
TTFN,
