I did not know that Rana Pratap and Prithviraj Chauhan were from South India.
I also did not know the JC Bose, Jayant Narlikar, Vikram Sarabhai, Homi Bhabha, Bhatnagar etc. were/are from South India.
Since you claim some " facts ", can you provide evidence for them?
How about bigoted South Indians like you are sent back to Egypt from where you came into India? But rest assured - unlike you, my heart and mind have not been corrupted by hateful nonsense passing for " facts ".
