On anthropomorphising, the established view has more guilt than the new
view.

That is just the perception that you are missing! Bugs don't
automatically make a mess! Those that don't, don't have their antigenic
signatures fast tracked to aggressive anamnesis. Pathogens DO make a
mess. That is why their antigenic signatures are fast tracked into
aggression.  I contend that almost everything we have regarded as a bug
hunting system can be interpreted as a mess (other-than-healthy-self)
seeking system. You might say this is just semantics BUT it does stop
perceptions being driven up blind alleys.

Agreed but I want to keep things relatively simple here. My response is
to leave that for others with more knowlegde to tackle.
