Oh well, When I was in Seattle we used to run across these weird sardar-ji. Mostly from Vancouver or Toronto. They own farms or orchards in Canada. So after every harvest season, when they are flush with money, they used to go to India to buy some property here and there and to do exactly what is being shown in this thread.
Mostly this means few weirdos with Khali - Sthan (literally means empty space) in their head used to come to these bullshit conventions and were treated with liquor from Phoren or some trinkets from Canada. And they chant few slogans and go home. After than no one used to give shit about it.
BTW, most of the sikh community in states and canada, which is next door to Seattle absolutely hates and detests Pakistanis -- mostly for stealing their identity and business but also for stealing the birth place of Nanak Sahib. So Pakistanis rest assured if Khalistan becomes anything, you will be losing Punjab and Sindh.
Oh lastly before anyone asks -- Sikhs, all those whom I have met, have no issues with Hindus because their paths seldom cross -- most of the Hindus in US/Canada are service class folks while sikhs are small/medium business owners. They have issues with muslims, specially Pakistani muslims for they are often confused for Pakistani and have to bear the brunt of that. The biggest issue they have is with Gandhi-Nehru family -- for obvious reasons -- which is on decline and is losing any popularity in India.
