Besides Hindus are generally tolerant and I don' think most feel seriously 'threatened'. BJP's most intelligent move would be to discard liabilities like RSS, VHP and so on and try to become a true centre of right party on the lines of the Tories in the UK. As has been the case with most parliamentary democracies, there will be counterbalance in the form of Labor. That space was filled by congress somewhat until their scams and hubris brought them down. And that's why I think the rise of AAP is inevitable. AAP right now is like the hardline labor under Tony Benn in the 1980s. And right now the situation is similar to the rise of Thatcher (= modi now) against them -(if the BJP has brains enough to understand). Eventually Labor had to reinvent as 'New Labor' and rose under Blair. I think that might happen to AAP. Kejriwal is very much like Benn, a more 'pleasing' leader ala Blair might eventually become the face of the party and that's how it will eventually rise, making it easier to shed some hardline stands. Speculating basis a comparable history.
