20th century belongs to America but mind it 21st century is going to be ours (Indians) %u2013 by Swami Vivekananda (at the time of Chicago visit)
People of India know which is right & which is wrong, who is secular & who is non secular,
It is our (Hindus) mistake that we are tolerating people like you, who are leaving in India but never believe on Indian tradition & culture.
As per research 49 civilization came and disappear from the globe earth but for your information only we Hindu survive in every respect and in every situation from last 10000 (ten thousand years) %u2013 take example of Egypt civilization, Maya, Humpi, Bebilonia etc etc all disappear. Now the question can be asked how we survive. The answer can be that our tradition, customs and believes are not based on superstition but based on science which normal person cannot define or describe, to define that one will need the knowledge of ultra modern science.
If person like you burn one or few copies of Manusmriti, nothing is going to happen to Hinduism, it will survive in the same manner. Your burning idea remind me about the burning of Nalanda University library in 15th century by muslims invaders.
Mind it now Indian karnatik music, Indian yoga, Indian vegetarian curries etc etc are concurring the world and this is a sign of our prosperity.
