To repeat myself from earlier: If you object to people rebutting this 'straw man', then perhaps you should try and stop people from proposing it. You can't call something a straw man simply because it's not what you personally mean by the word.
My point in the above post was: Zuk is positioning herself as if she were attacking Paleo as a concept, but all she's really attacking is the mis-application of information by some members in a larger group. I call that a straw man.
Evolution tends to operate as a hill-climbing strategy (not to say it cant clear away exising design details) so it often produce (non-fatal) 'bugs' in its designs that never get fixed.
