Scheduled Castes In Sikh Community
The social universe of the Sikhs at that time was defined by, what was described as ‘Sanatan Sikh tradition’ – primarily a priestly religion. Giani Pratap Singh, later the head priest at the Golden Temple, noted that the mazhabis were forbidden to enter the Golden Temple for worship; their offering of karah prasad was not accepted and the Sikhs denied them access to public wells and other utilities [Pratap Singh 1933:146-47, 156-57]. When a group of Rahtia Sikhs tried to enter the Temple in the summer of the year 1900, “the manager of the sacred establishment, Sardar Jawala Singh, ordered their arrest. The reformist Sikhs who accompanied them were abused and finally beaten up... Because one of the defining characteristics of a sacred precinct, in the eyes of the Sanatan Sikhs, was its ritual purity” [cf Oberoi:1994:107].
Sanatan Sikhi - Distortions of Sikh History
or from their own website, you can see that they equate akal takht and AKJ both with nirankaris! 
and that they hate "dirty foriegners". we also know from the experiences of Vijaydeep Singh here on SPN that they are casteist and do not distribute Amrit equally. based on the fact that they do not allow women into their orders and are celebate, we can see that they are also sexist. does any of this sound like Sikhi to you?
yes, they dress cool and have great looking dumallas. it's fascinating how they like to keep the "old" traditions (as they know them, not as Gurus taught). but can we really consider them Sikh?
they themselves say that they belong to "sanatan dharma" (hinduism)...
read through the sarbloh website. i think most sikhs would be upset by what they read. especially with their unfounded hatred of Akal Takht and AKJ... they think only THEY are the "true" sikhs and anyone else who ties a blue dumalla is an impostor or fake.
