If you read the article carefully you will understand what these people are saying, which is, it is good governance which paid off for Modi and not the promotion of RSS agenda (read communalism, violence and riots).
In effect what they say is that promotion of RSS 's agenda would have been a fiasco.
.. and here you are, asking RSS to lead the nation!
Religious fundemnetalism may pay in Talibanist Afganistan , but not in India. Even Modi realises this! But you don't.
