Me feel that this "manuvadees" means to Manu Smriti related. We have to listen and understand all facts in detail, then we can see that very many good things conved by the bad ones as per the present situation. We only select the good things.
More over, we can change and amend all the old ones according to the present trend which go to benefited the majority and not affected as bad against to any one. We have to understand this is the full flazed demoracy.
