Lalli is considered an untouchable, a dasi. Based on everything we've seen on the show, she cannot go to a mandir (fear that she will make it "unpure", "dirty"), has restrictions imposed on her (where she can cook and eat), and is viewed in a bad light by townsfolk, through no fault of her own.
Now, Lalli is wanted to give birth to a waaris??? Lalli the dasi, Lalli the low caste girl. Does this even make sense? To have a waaris from a dasi? In India, doesn't that make the child "unpure"? Why didn't they have Shekhar remarry?
Look I don't get this whole caste thing--in my opinion it is downright wrong to brand people at birth and keep them in their "place", subjugate them all their lives. But thousands of years of practice cannot be broken--it never will be. by the way. All human beings need something to make them feel superior to someone, and allow them to forget that there is someone sitting on top of them too.
What do you all think? I would love to read your responses.
