I suppose society needs weight on both ends of the scales. I'm no more in favour of a society that condones fundamentalist or Biblical law any more than I am in favour of a society that condones Eugenics or Unrestricted DNA experimentation.
In many ways Religion, in it's strictest form is a neccesary 'dead weight' that stops science getting too carried away. when Einstein suggested Nuclear power, he did not really dream it would be adapted to create a weapon, many scientists are like that, blissfully unaware of the possible other uses of what they research, or firmly in the belief that no-one would be stupid enough to. Theres always someone stupid enough to.
That's why the whole 'religion and morals' thing will never really be sorted out, Each one provides a Dynamo that powers the other in some way. Take a look at how much energy has been put into solidifying our concepts of Evolution, thanks to ID.
