I don't agree calling them archaeos is necessarily insulting per se, it's all about context as they say: loads of archaeos use the term for instance. I also don't think calling them things like MPP is usually wrong - it's affectionate and signals everyone knows them, which is a complement - and again, archaeos do it.

The point being, Buck, ;) so long as those terms are used where there's a general climate of respect for archaeology and science the terms are harmless. If on the other hand they are used where the climate is otherwise, then of course I agree with all you say wholeheartedly.
