It is not clear from your statement what Sonia is making better - and what difference you are talking about. Also your statement "BJP is pumping hatreat for the muslim community" is completely wrong - there are many Muslims in BJP.
The Babri Masjid was built on top of a Hindu-shrine by the Mughals - with the single purpose of destroying the Hindus and their faith. Such inequalities against the Hindus should not exist in modern India, and this historical blunder should be undone. If you mean "muslim appeasement by downtrodding the Hindus" as "better India", then that can not be supported. As Hindus are very tolerant, that's why you can freely say and mean something like this. If you say something like this agains Muslims in Saudi Arabia, Pakistan or Bangladesh - you would have been doomed.
