Leave it Jai, theyre just provoking you in to one liner response, so they can make themselves look right and you wrong. theyre not going to listen or change.
For khalistan info and good response to some these questions please ref:
http://en.wikipedia.org/wiki/Khalistan
I've read loads on khalistan and indian history, and spoken to ppl who were in punjab in late 70s and early 80s, and ppl who lived in amritsar in 84, and in conclusion i am not in favour of khalistan. last thing ppl in punjab and india need is more violence and terror, extremism. i thing most ppl in india have changed now and they dont want those days back. but its a shame, some sikhs living outside india, want all the trouble back.
so Jai just leave, these type of ppl are a part of life. let them carry on, there opinion is theres ours is ours.
