I think every now and then Bollywood has made some female centric movies. Guddi, Seeta Aur Geeta, Aandhi, Khoobsurat, Khoon Bhari Maang, Chaalbaaz, Umrao Jaan, Damini, Phir Teri Kahani Yaad Aayi, Fiza, Zubeida, Astitva, Chandni Bar - these and others I may have forgotten are all female centric movies where the woman took center stage.
Some were major hits as well. I think recent hits like Queen, Kahaani, Dirty Picture and English Vinglish have broken barriers of mass appeal. But I think credit is due to all actresses and filmmakers who have attempted to give women equal footing.
You make a good point. However, when it comes to minority representation the issue is more complex.
Consider this. The population of Ferguson is 52% black. Yet they make up less than 5% of the administrative and police force. Is it the black person's fault they are unfairly represented and discriminated against? To a certain extent yes, there are issues within the black community that need to be addressed. At the same time it would be foolish to ignore the history of slavery, centuries of white dominance and generations of socially ingrained racism.
Women in India face the same challenges. For centuries she was seen not as a human, but property, first of her father and then her husband. Women today are born into generations of patriarchy and male dominance. Women still live in a society ingrained with extremely strong definitions of how an ideal woman should be. In such a world it is not easy to stand up one day and decide to change things. Sometimes it is difficult to even see that there is something wrong because from the second a girl is born, the patriarchal definition of women is taught to her by the world around her.
Yes it is absolutely shameful and disgusting that a North Eastern Minority woman cannot be faithfully represented in Indian cinema. At the same time it is commendable that Mary Kom is a well-known and celebrated woman, and she gets her story. Today a woman is represented, if we keep pushing, someday the minorities will also be well represented too.
