No Indian school has any text book which says muslims are your enemies, they are kafirs who need to eliminated. Your schools do. The only time pakistan is ever mentioned is in history books and the Indian freedom struggle with chapter ending with two nation theory of Jinnah.
Rather our NCERT books are filled with secularised aman ki asha pro max content that a Pakistani can't imagine.
What?
I know about Muslim girls in schools in India who faced similar harrassment long before Modi. This is generally the result of British Divide and Rule policy which was initiated after the 1857 Mutiny. And, it is also evidence of mass stupidity among subcontinental people who fell for the manipulation. They began to view religion as if it is membership of a singular ideological political club or party. Even kids aren't spared from political abuse which means they don't have the right concept and understanding of religion to begin with.
I discovered the Two-nation theory ideology on the internet and I matriculated from Indian School in the Gulf. Don't remember reading anything about it. I faced no discrimination there. That was decades ago, don't know if it has changed after the rise of Hindutava ideology.

[Markandey Katju who wrote in the Pakistani paper The Nation in 2013:[16]
Up to 1857, there were no communal problems in India; all communal riots and animosity began after 1857 ... The Muslim rulers like the Mughals, Nawab of Awadh and Murshidabad, Tipu Sultan, etc were totally secular; they organised Ramlilas, participated in Holi, Diwali, etc. Ghalib's affectionate letters to his Hindu friends like Munshi Shiv Naraln Aram, Har Gopal Tofta, etc attest to the affection between Hindus and Muslims at that time. In 1857, the ‘Great Mutiny’ broke out in which the Hindus and Muslims jointly fought against the British. This shocked the British government so much that
after suppressing the Mutiny, they decided to start the policy of divide and rule (see online “History in the Service of Imperialism” by B.N. Pande). All communal riots began after 1857,
artificially engineered by the British authorities. The British collector would secretly call the Hindu Pandit, pay him money, and tell him to speak against Muslims, and similarly he would secretly call the Maulvi, pay him money, and tell him to speak against Hindus.
This communal poison was injected into our body politic year after year and decade after decade.[16]]
