RSS is the mother Hindu organization (non-politcal). VHP too is non-politcal, is one of the shoots. That is, they do not contest elections. Elections and government are left to BJP.
Yes, Bhindrawale was propped by Congress, Giani Zail Singh, and Indira Gandhi against Akali Dal. Then Pakistan entered the scene. Bhinderawale was then, sort of, a prisoner of separatists. Yes, Indira Gandhi made the same mistake that Pakistan made in denying power to Sheikh Mujeeb. They did not want Akali Dal ruling Punjab forgetting that this is a part of democracy. Governments change. For the last five years Akali Dal and BJP are in power in Punjab and there is no problem. Indira Gandhi did not hate sikhs. Sikhs were always part of her government. Buta Singh was the home minister at that time. Now if a section of people embark on separatism, it is natural that the Nation will not take it kindly. Don't bring Baba Shri Chand into it. That was in 16th Century and he had nothing to do with politics. Of course, there were a lot of sikh officers in Army and Police who conscientiously did what was required of them to do. Christians and Indian Muslims were not involved in Punjab separatism, of course, there were a lot Muslim infiltrators sent by ISI from Pakistan who were disguised as Sikhs.
Well here are some quotes by Sant Jee
"I am not for or against Khalistan, but if we are given a separate Sikh nation we will not make the same mistake as '47, we will certainly take it."
"Indira and Congress have labelled me a terrorist. If getting Sikhs to take amrit and stay away from drugs, alcohol, meat, abstain from trimming their hair and beards, defending the honor of our sisters and the spilling blood of the shaheeds is the work of a terrorist then yes I am a terrorist."
'My mission is to administer Amrit, to explain the meanings of Gurbani and to teach Gurbani to those around me; ... and (to tell people) that a Hindu should be a firm Hindu, a Muslim should be a firm Muslim, and a Sikh should be a firm Sikh'. His preaching was based on love. He said: 'If we speak to someone with hatred and try to assert our superiority, it will create hatred in the minds of everyone. So long as we have the spirit of love, so long as we have the support of Satguru Hargobind Sahib, the Master of Miri and Piri, is there any power on earth that can subdue us?'
'Nashey chaddo, Amrit chhako, Gursikh bano (Give up addictions, Take Amrit, Become good Sikhs)'.
"I am not opposed to Khalistan, nor am I for it, I seek only equal rights for Sikhs."
Here is the history of the movement; it seems based on Anandpur Sahib
On October 16, 1973 the Akali Dal, when it was not in power, passed "The Anandpur Sahib Resolution." The major provisions this resolution were; regional autonomy for Punjab, return of Chandigarh to Punjab, special status for Sikhs in the Indian union, a supreme court review of Punjab river waters, return of the Punjabi speaking areas to Punjab, return of the administration of the Punjab Electric Board as well as the three thermal headworks to Punjab, provision of a fare share of electricity to Punjab, and some minor religious demands.
With a view to win over Hindu majority of North India and Punjab, Mrs. Indira Gandhi mischievously exploited the anti-Nirankari movement in Punjab to create communal antagonism between Sikhs and Hindus in 1980. State terrorism against devout Amritdhari Sikhs was started in Punjab through her stooge Chief Minister of Punjab, Darbara Singh, during 1982. As a reaction to the Police terrorism on Sikhs, the devout Sikhs started taking revenge on Police and officials who ordered persecution of Sikhs in 1982-83.
From October 1983 to June 1984, is a story of political manipulations and mischievous designs on the part of Indira Gandhi to destroy the Sikh faith and exterminate the Sikh people with a view to win over Hindu votes in India.
Indira Gandhi throughout negotiations between Akali Dal and Centre never let the negotiations reach finalization or settlement because she had an ulterior motive. She let the Punjab crisis drag on in order to rally the state's Hindus behind her and in order unify the Hindu majority of North Indian states, all of whom were concerned about the growing shrillness of the Sikh agitation. The Hindu psyche had been poisoned so much against the Sikhs through communication media and mischievous political manipulations that they wanted the Delhi Government to deal more forcefully with Sikhs. By stone-walling the Sikhs, Gandhi was consolidating her position with the Hindu majority , particularly of North India, whose support she considered necessary to win in national elections that were to be held January 1985.
and here is a quote by Gandhi
"I don't give a damn if the Golden Temple and the whole of Amritsar is destroyed, I want Bhindranwale dead" (Indira Gandhi, communicating to General Vaidya during operation Bluestar)
Can you hate someone so much that you want to kill them because they wanted more rights? Although if we look at the other side of the coin, how did the Sikhs know this was going to happen and why did they choose the Golden Temple of all places?
'if the Indian Government invaded the Darbar Sahib complex, the foundation for an independent Sikh state will have been laid.' Bhindranwale
Your father is as ill-informed as you are. Sure, correct information about India is not available in Pakistan. A whole lot of sikhs enjoy special facilities.
