If someone is Nepali, sooner or later they will get their citizenship. They might have to do some extra work if they never bothered to get a birth certificate or register themselves at Ward or something but eventually they will get their Papers.

If you change the law for any mother to give citizenship, tarai will get another 40 lakhs of indian citizens in another 5 years. Google little bit on Citizenship hardship countries and you will see Nepal is not listed as a worse country to get one.

Biologically men and women are not equal and are indeed different but we can work towards making the rights equal between the two.
