I think its good to question ones culture and views. Definitely better than "andhabiswas". Questioning does not mean we are discarding everything, we might discard some practices such as dowry but only after reasonable contemplation. This is healthier than blindly following traditions.
Also, I do not think we are the first generation to do this. Each generation goes through this phase and changes the direction of the mass culture a little bit, What triggers such questioning might be different. Democracy might have been one of such triggers, To us it is experiencing western lifestyle.
