I don't dispute that. I'm saying it's far from a given that a girl will
want out. If she's truly not okay with the decision of the arrangers (and if she doesn't have any influence over them) or if the marriage turns out badly, it's a tragedy, but given the system's prevalence even outside India, there's no reason to suspect that cases like that are the majority.
Bride burning is different. Whatever the motivation, it still results in one or two deaths, and so it's a phenomenon worth fighting against.
Again, same with the dowry. Not forced, but if you don't pay the daughter is treated very poorly and seen as inferior (unless it's a love marriage)
Which is probably why dowry is technically illegal in India these days (not that it really stops people). Again, the problem is primarily regional. Places in India where women's work is still valued (mostly the south, I believe), dowry still functions as intended: the bride's inheritance, as she's leaving to join another family. Of course the system is open to abuse, but it's the abuse that is the tragedy; the system itself isn't inherently sexist.
