Unconventional ways are initially criticized , resisted and not approved even to be experimented,tried-that is the ages old strategy of status-quoist society which seldom responds to time and changes in the required  ratio and proportion.
Progress in all and every field is not the repetition of old belief or practices but a step forward ,backward  or a step which was never taken before.These never before propositions,once initially resisted, deprecated , rubbished out are the game changers and progress pillars.
