Don’t explain it to Pakistanis, whatever you tell them is wrong only they are right. Ramayan is a part of our ancient history and culture, plus Bhagwat Gita has nothing to do with Hinduism but is a book of moral values which everyone should read once irrespective of religion.
And no one is banning Quran for them, they will be taught that also, but in my opinion if they are taught Ramayan and Gita they will connect to their roots in India instead of remaining into a delusion that they are Arabs, Turks Mughals. It is my opinion only.
