I agree some rules make sense, some dont, some change with time, some dont. what is acceptable in society changes, not always for the best but it does change. what is acceptable in a society changes over time, not too long ago ladies with shorter hair styles were called "parr katti kabootri" type of things :) so change is inevitable and with that change old rules become obsolete. Not all change is positive I suppose, and people dont have to embrace all change.
to cling on to 'rules' as divine revelations would have meant we would be living like we did hundreds of years ago, and believe me rules were different back then ( i know, I was there :) )
You are brave to admit you are a dinosaur :)
In terms of divine revelations I would argue that you would be surprised that NOT a lot has changed in people. The even more modern of ppl when in a real jam or can't control their circumstances turn to older rules and regulations because it what they were brought up in. But that's a discussion for another thread.
