mathanxiety - the other very sound reason for not doing VE's is the fact that in many women find them extremely distressing and intrusive, and because of this they may disrupt the normal hormonal cascade of labour and result in a more difficult, prolonged and painful birth.
MistyValley - what would be the point in telling women all the things that can go wrong with a vaginal birth if you aren't offering them any alternative to trying for a normal delivery?
In any case, labour is a normal physiological process. Nobody sits us down and tells us about everything that can go wrong when we eat (choking, indigestion, food poisoning), or empty our bowels (anal fissure, constipation) do they? So we can consider choose whether to be tube fed and have a colostomy instead? 
Jeez, what's the world coming to? 
Ushy - can't see the problem with the use of the word 'normal' to describe a birth which happens spontaneously.
'Normal' walking is walking without the aid of a stick or zimmer frame.
'Normal' defecation is going to the toilet without needing manual evacuation of your stools, or laxatives.
'Normal' labour is labour which starts and is completed without drugs or instruments.
So no judgement there. Just an acknowledgement of the physiological norm.
