Educating the youth on Sikhi, overcoming the Drugs epidemic in Punjab, getting rid of caste system, spreading the message of Guru Nanak to those Indian communities that have suffered so much because of the caste system, electing better leaders, educating Indians of all backgrounds on sikhs issues, telling them about what Bhindranwale actually stood for, educating them on 1984 Genocide and educating them on the atrocities central government committed in Punjab are just some of the issues we need to focus on instead of Khalistan.
And the reason why we need to focus on the above listed issues is that it'll create a foundation for Sikhs in the future to work with where they can force the central government to listen to Sikhs just due to the sheer number of supporters asking for things such as equal rights, justice for 84 genocide victims and general issues related to whole of Punjab. Look how central government enacted different laws when protesters shut down Delhi over the Delhi bus gang rape victim. And look at how many global news agencies picked it up. Now imagine that kind of a protest all over Punjab, Haryana, Delhi, Mumbai etc etc by Sikhs demanding equal rights..
That's what we need to aim for instead of spending our resources and time on Khalistan (which right now is far more unrealistic thing to achieve than the above listed things).
