What is extreme nationalist ? India is a 5000 year old civilization.

Does banning triple talaq and medieval Islamic laws count as nationalism ?

Does bringing modern 21st century laws (including women equality and inheritance laws) to a territory given special status for merely political reasons count as nationalist ?

The condescending attitude is very off putting. If you base your opinions on the international media portrayal of Indian politics i would definitely say one thing is extremely lacking: nuance, it is mostly agenda driven drivel.
