I'm not a fan of 'feather in your cap' conversions where you tally up numbers and then win the game. I don't know if I'd say it's unethical. Some tactics surely are. But, all-in-all I don't know why people get their panties in a twist about it. That being said, if you're trying to convert people, you should probably be respectful and not piss off large groups of people in the area where you're living. Also, the whole sugar in milk imagery is a romanticization of Indian inter-communal relations. Babri wasn't quite sugar.
