Lol what are you talking about?Bollywood is basically run by Punjabis and it is a surprise to me that they would refuse another punjabi that is sligther of darker tune.
But majority of the racism is directed at central and southern Indians..
Punjabis, Mashtra, Bengali and other northernely Indians get representation but never Central and southern indians..
India is also the most racist country in the world where the few whites of the north treat the rest of color in central and south like piss dirt.. The reason for this is because India has never been a unified country or people.. It is 32 countries continent with different races and ethnic groups and to be honest it is like Africa forming a country where the north Africans are white and the rest is ignored
Rekha,Hema malini, jaya prada, Sridevi, Deepika, Aishwarya, Genelia, Ileana, Jacqueline (technically sri Lankan), Shilpa shetty, vidya balan, tabu, dia, are some south Indian Bollywood actresses famous in Bollywood.
