Here you have bombings by sikhs:
1991 Global Terrorism: Asia Overview
Separatists also have stepped up attacks against journalists. In January, Sikh extremists declared war on the press in Punjab and forced reporters to stop calling them terrorists. Newsmen critical of Sikh terrorist tactics received death threats. Kashmiri groups also assassinated journalists, including the editor of the Urdu daily Al-Safa in April. Although Assamese and Kashmiri terrorists limited their operations to their respective states, Sikh terrorists expanded their operations outside Punjab. In late January, Sikh terrorists bombed a movie theater in New Delhi, injuring six people. Sikh extremists probably also were responsible for a bombing in New Delhi in late April that killed three people and wounded eight. In mid-October, a Sikh bomb killed at least 55 people and wounded 125 others at a Hindu festival in Uttar Pradesh, near the Nepalese border. In late August, four members of the Khalistan Liberation Front unsuccessfully attempted to assassinate the Indian Ambassador to Romania in Bucharest; Romanian antiterrorist experts killed one person and captured the other three. This was the first Sikh terrorist operation outside India since 1987.
And as I said , Sikh extremism has been crushed by sikhs themselves in Punjab and India. There is no violence or anything whatsoever in Punjab now, and things are very peaceful in India now.
Sikhs themselves are understanding that they have been manipulated by Islamic pakistan for their own ends and are wiser now.
Also I wish to state that even these few sikh militants never killed the bahais, the zoroastrians, the jews, the buddhists, the jains, the christians, the assyrians and raped their women any where in India or the world, unlike the islamic fundamentalists.
There are substantial sikh minorities in the U.S, the U.K. , Australia, and in all these countries they are perceived as a hardworking , industrious, prosperous and well-educated community with very low crime rates , unlike the islamic communities in these countries.And the buddhist and the hindu minorities as well share these same charecterestics as the sikh community and this has been proven by sociological research.
This in no way excuses the behaviour of so called Muslims committing such attrocities. What makes a terrorist? The experts say it is not religion but economic hardship, oppression, lack of education and a feeling of helplessness.
Yeah sure, so Osama Bin Laden was a poor man. Great logic. Same with Aurangzeb, Babar, Allaudin Khilji and other religious despots.
And we have numerous islamic terrorists , who are well-educated, which includes bin laden, aurangzeb and babar, and ayatollah khomeini. Lack of education is not the reason for islamic terrorism, but the reasons I have cited above in my previous posts.
