I did answer it already. It seem almost every Indian voted Indian first and Hindu later. It seem many people are confusing Hindu nationalism with Indian nationalism when they are actually two different things. When you say you are Indian before Hindu then you treat all Indians even low caste Hindus and dalits or any other religious minority equally and give them same social status and dignity without having any discrimination, bias, bigotry and hatred for them or their beliefs at state as well at public level. While Hindu nationalism is totally opposite ideology . Let me quote Shri Guru Ji here whom your PM Modi take inspiration
In We, or Our Nation defined (1938), he stated:-
“ The non-Hindu people of Hindustan must either adopt Hindu culture and language, must learn and respect and hold in reverence the Hindu religion, must entertain no idea but of those of glorification of the Hindu race and culture ... In a word they must cease to be foreigners, or may stay in the country, wholly subordinated to the Hindu nation, claiming nothing, deserving no privileges, far less any preferential treatment—not even citizens' rights.
Is this Indian first or Hindu later philosophy or Idelogy?
