Sikhism was set up by Hindus that were not happy with being Hindus. they separated for one simple reason. they were warriors and they wanted a religion that was saying they could fight for what they belive in.
conclusion; set up by stupid warriors. not very good base for a religion.
Actually, in fact, the founder of Sikhism, Guru Nanak Dev Ji, was very peaceful and did not fight in any battles or wars. He was not a warrior, he was a very intelligent man with very different beliefs which still exist through the religion today, and were actually taken up by Western society after his demise. Equality of religion, freedom of speech, freedom of practising religion, no one person is better then any other, everyone is subject to the law etc..
The warrior of Sikhism, or the Khalsa Panth, only came in a couple of hundred years afterwards when the Sikhs were at war with the Mughal Empire and the Afghans, both of whom they defeated. Read up about Guru Tegh Bahadur, and you would see he sacrificed his life to save several thousand Hindus, whom were of a different religion and have different beliefs. Also, the militarism of Sikhism is especially significant with Guru Gobind Singh Ji.
Also, Sikhism was not set up by unhappy Hindus, it was originally followed by people who thought that the beliefs Guru Nanak Dev Ji had were much more humane, realistic and generally better then the Hindu beliefs. Sikhs do not beleive in a lot of Hindu beliefs, ie, they have a LOT of different gods and stronger entities, whilst Sikhs just have the one god. Sikhs have a different beleif on the caste system, as they do not believe in it at all and think it should be removed from Indian society, whilst Hindus still follow it. Sikhs also believe in teh teaching of science and technology, whilst some Hindu beleifs clash with science. Sikhs have to follow the 5 K's, whilst Hindus dont even have any mention of the 5 K's. There are many more differences, but you get the drift.
If your gunna try disprove a religion, and least state the truth, adn facts rather then your own uniformed personal beliefs, which are frankly just wrong.
