If they're presenting the theory from a standpoint of apparent understanding and accurate portrayal - how does criticising the content of their posts then not criticise the theory?

If the opposition (creationists) are in fact as ignorant in our understanding of these things as has often been made out - one wonders why the need for such a backpeddle here to excuse the evolution members own possible errors, for fear it might poorly reflect or expose the theory itself?

I'm considering that evolution is a game the opposition can never win - based upon the excuses and changes of definitions that game makers/marketers continue to apply to it.
