Depends on the region too. Part of my family is from a landowning/feudal caste (Chaudhary/Jatt and Pahari) that is traditionally Upper Caste but successfully lobbied to become counted as OBC/Lower Caste in order to avail affirmative action benefits.

The Jatts side got reservation thanks to Congress [0] and the Pahari side got reservation thanks to the BJP [1]

Edit: Lmfao this professor (Kuldeep Meel) is Jatt from Hisar/Jhunjunu side. Jatt is not lower caste. Ask my extremely casteist Jatt grandfather who uses Dalit caste names like Chamar, Gujjar, Kanjar, or Balmik as slurs. We became OBC because we burned shit down. The people who actually deserve some form of Affirmative Action didn't get any.
