I said this a bit differently in another comment but I'll ask you this - would you still support Aadhaar if the party in power was not the Bjp? Remember that the party in power will inevitably change at some point but this project will remain. Would you be able to trust any party besides the Bjp with being in charge of this project? If you would, well I won't argue with you, if not you really have to think about the implications of what is happening.
