Ok fair enough afriend.
1. Punjabies can't buy land in HP, Haryana and Rajasthan.
2. Sikhs are forced register thier marriges under Hindu marrige act, Pakistan has Sikh marrige act.
This just couple of examples, some of them goes back to 1947 such as what Nehru offered Sikhs to join India and when we finally gained indipendence, Nehru didn't kept his word.
