Indian men generally grow up seeing their mothers do household chores, cooking, cleaning and so on. They expect the same from their working wives and girlfriends later, not realizing that these women were brought up in a similar way as well. Culturally, most mothers-in-law want grandsons, not granddaughters (as evils like dowry are still prevalent), forcing their daughters-in-law to abort girl babies.
The USP of my argument is this : The sex ratio of women to men in India is 914:1000. If a girl child is killed before birth, it shows that men and women are not being treated equally. Women are unwanted and that is inequality.
