Sikhs want Punjab to be its own country, separate from India. India post Congress is ruled by Hindu nationalists who want to rewrite history books and erase anything positive that happened in precolonial India (which wasn’t really a country in the modern sense, but a changing set of integrated states) under non Hindu rule. The BJP are fascist shit stains and literally ordering hits on Sikh activists abroad for trying to promote Sikh separatism. There’s really not much more nuance than that. Fuck Modi.
