Then the Nation should stay away from INC as well. Picking INC ignoring 1983 is no better than picking BJP ignoring 2002. People like Jagdish Tytler continue to a part of the N-G family coultry.
My point is your "Modi is a Muslim blood-drinker" argument is moot, especially if you pick the Nehru-Gandhi family over him. Both entities have a history sheet, and if you choose to ignore one's history and merely look at their administrative merits, then be prepared to do the same for the other, too.
As far as administrative qualities go, Modi is arguably the best CM the country ever produced, while Rahul Gandhi continues to be the Justin Bieber of Indian politics.
