Sikhs tried that peacefully for decades before 84(Punjabi sooba movement, waters issue and other demands). Most Indians think everything just started in 84 or with Bhindranwala. All the peaceful means were finished when in 1978, 13 Sikh protesters were killed by Nirankaris who were allies of Indira Gandhi. Sikhs tried all sorts of ways to have the Nirankars punished through the court system. When nothing was accomplished, that is when Sikhs began to take up arms to defend themselves. Sri Guru Gobind Singh Jee Maharaj has said in Zaffarnama letter written to Aurangzeb that "when all peaceful means have been used, it is righteous to raise the sword(as a last resort)".
Just look at your own history. Didn't Krishna and the Pandavs also take up arms and wage war when all peaceful means failed? Didn't Shiva jee Maratha also take up arms to fight against the unjust government of his time? Most Indians today have been brain washed by Mahatma Gandhis Ahimsa philosophy which have no base in Hindu Dharm.
Democracy is only advantageous if you happen to belong to the majority. Sikhs are less than 2% of India's population. Sikh cannot get any justice through democracy, and the fact that those congress ministers who led anti Sikh riots in 84 are still living a luxurious free life.
That statement is not supported by Hindu Dharma. Was Lord Krishna and Arjun not following dharma when they assassinated Bhishma, Karna, Drona all of whom were unarmed? those men were killed because they were on the side of Adharma(the side of Duryodhan).
No, Dyar was on stage giving a speech when Udham Singh assassinated him. At that time too, most Indians (including Gandhi and Nehru) condemned the assassination and declared Udham Singh a terrorist. But decades later the same Indians (including Nehru) declared Udham Singh as a great man.
The attack happened right on the Shaheedi purab of sri Guru Arjun Dev Jee. That was when Sikh from all over India come to Harimandir Sahib to observe the holiday. Indira gandhi chose that day so maximum number of Sikhs can be killed. If the attack was to happen why didn't it happen a day before or after the holiday? secondly, why was there a media black out in all of Punjab. What was Indira Gandhi trying to hide from the world media? Why was the Sikh reference library containing priceless historical artifacts burnt by the Indin army?Once the Sikh militants were killed, why did the Indian army begin to kill Sikh pilgrims(elderly, children, babies) and rape Sikh women? Even the Afghan army of Ahmad Shah Abdali was not this cruel when they attack Harmandir Sahib.
