was it just hindu nationalists?

The Associated Press reported

Sonia Gandhi said she would "humbly decline" to be the next prime minister of India, a decision that followed Hindu nationalist outrage over the prospect of a foreign-born woman at the helm of the nation.

In my opinion, however, the outrage over a foreign born person becoming PM of India was across the board, not restricted to a particular segment of the population, either an income group or a religion. Another case of how improper perceptions even in the so-called "well-read" press propagate because of the mass appeal of an organization such as the AP. Hopefully, this image shall change
