I just want to give an outsider perspective.
While you will have no doubt to accept the fact that all the Hindus and their families are always ask to revere Gurus and Sikh as warriors of Hindu faith with highest respect. The sikhism until the time of Shri Ranjit Singh and Harisingh Nawla had identity of a unique sect of Hinduism.
However, the Singh Sabha on behest of British and their appointed scholars not only split the Sikhs from Hindus... but also made the inclusive Sikhism as an exclusivity Sikhism. Even if you get hold of any Rahetnamas or any declaration by SPGC or most of the Sikh Groups it is based upon Anti-Brahmin or anti-Hindu ideology, just to ensure that they maintain their separate identity. Lot of potraits for Gurus with Tilak were removed, most of the language is that "do not follow this because Hindus follow this". Sikhs started questioning the literatures and at the time of Guru Gobind Singh as corruption by Hindus(when it is a fact that most of the scribes of Gurus were also Hindus, there was no such issue until the time of Raja Ranjit singh). Rather than reforming or giving space to Udasis or namdharis was it right to start executing them in Mughal ways?
Detaching Hindus and generating hatred towards hindus, instilled insecurity and mistrust among both communities post singh sabaha and lead to so many events of evil and division.
It burns my heart to understand why couldn't the mainstream sikhs identify the big flaw in the singh sabah and ISI inspired Khalistani events of exclusion and hatred, and let their influence into anti-Hindu rahetnamas.
I mean do they expect Muslims and Christians who are based upon ideology of hatred and exclusivity to convert to Sikhism?? as opposed to Hindus, who gave away one of their sons to Guru when the Sikhs were reduced to low numbers. Though I am not from Punjab, but I have personally seen most of the Punjabis are More Guru Bhakts then being Hindus. can Sikhs find such following among Muslims and Christians??
