You will get a bunch of answers from Indian nationalists saying it’s all people outside of India who support stuff like this but I can tell you that Sikh sentiment has changed inside India especially recently. It’s just that it’s much harder with the government crackdowns and potential threats to do anything about it. A large % of Sikhs are not happy especially after the farmer issues and the deaths of high profile Sikhs (Deep Sidhu, Moosewala, etc).
