Honestly I have no clue what are you talking about but you are heavily misinformed...LOL.
It was Congress supporters that went on a killings spree against Sikhs to avenge the murder of Indira Gandhi. There were people from all community in that Congressi supporter's group. It was a political violence against a particular community but the attackers were supporters of a political party and not aligned to any specific religion. Infact, current BJP uses that Sikh massacre everyday in their political speeches to corner congress. Would they do it if it was only hindus involved?
Also what do you mean by 'was it Muslims and Christians desecrated Golden temple'? Why it is always about religion for you guys? Long story short but Khalistani terrorist Bhindrawala was using Golden temple as his terror hub...he hijacked the place, loaded arms and ammunition, staying there and marshalling his troops from inside the holy place. Indira Gandhi govt then asked him to come out and surrender multiple times as govt didnt wanted any blood shed in temple which will hurt religious feelings of Sikhs. But Bhindrawala was reluctant to surrender. Then Mrs Gandhi came on air in Dooordarshan, called for a curfew, pulled in Indian army, went inside the temple and killed him (known as operation blue star). Its a different story that Sikhs still felt insulted that their holy site was breached and that is why they killed Indira Gandhi few days later.
But I still fail to understand...isme only hindus killing sikhs kaha se aa gaya? Unless you are saying the Indian army only had hindus with tilak and were shouting 'Jai Shri Ram' who went inside golden temple.
