I had a Sikh roommate for 3 years and many Sikh classmates at the university. They were about as religious as non-Sikhs (my roommate was more religious), respectful and never bothered women. I am sorry to hear that your experiences fared worse. Alcohol? My roommate did not want to be in the room if I used a bouillon sachet with chicken extract that I had to stop. Neither of us ever touched liquors (not for religious reasons in my case).
So what if some Sikh youths are not religious and are hedonistic. Is this a “No true Scotsman” argument? Isn’t it normal in a modern society for youths to be less religious and grow more religious as they get closer to their mortality? Isn’t there room for cultural Sikhs/Hindus etc. who don’t place any emphasis on the supernatural?
My roommate brought up Sardar jokes on perhaps a couple of occasions. It’s OK in my book for Kushwanth Singh to tell Sardar jokes, for Russell Peters to tell Indian jokes and for Jon Stewart to tell Jewish jokes. Never heard of Santa Banta Ha-Ha-Ha till now. I did read of bara bajje jokes in a Kushwant Singh book.
What exactly does Khalistan achieve? What will it allow Sikhs to do that they cannot now? Impose a state religion? Is that the teaching of the gurus? (I read Sikh scriptures, here and there. I liked their open philosophical views which I thought were quite compatible with a modern society)
India is not yet a developed country. People of such regions are better off organized into large countries, as long as there is a fair constitution in effect. When splintered, they simply get taken advantage of on the world stage. While not robust, India has better leverage due to its size in ways that its neighbors (Pakistan, Bangladesh, Sri Lanka, Nepal) of similar development levels do not have. For richer countries, size matters less.
