Why should sikhs be ashamed.I have interacted some of these Punjabi Hindus and even though I am not from south the disparaging opinion they have about people from south always made me wonder where is the sense of one people, being part of one country one great culture is.Even I heard from these Punjabi Hindus it's better to break up the country.At least Sikhs are honest, these Punjabi Hindus deserve a kick in their butt.
