I think the divide and rule analysis is correct, but it's the establishment that's pitching everyone against each other (based on colour/religion/class). The two-tier policing and justice system is designed to disempower white people and stoke racial tension. I also think that your analysis of the Sikh and Muslim faiths is missing the historical reality of the two distinct groups (again to create tension and misunderstanding).
Sikhs were fighting the Islamic Mughal regime from 1621 to 1788. Out of ten Sikh Gurus, two were brutally tortured and killed by the Mughal regime for refusing to convert to Islam.
In response to Mughal tyranny, Guru Gobind Singh mandated the Kirpan in 1699. Defying Mughal laws that banned non-Muslims from carrying arms.
Sikhs have fought for Britain in both world wars (voluntarily) 150,000 in WW1, and 350,000 in WW2. They have been part of British society for a long time.
As for the Kirpan, most I've seen are small, blunt, curved decorative artefacts (they can't even cut cheese). They are harmless. However, there is no reason (religious or otherwise) to carry the sort of weapon wielded by Vickrum Digwa.
What does need to be addressed is woke two-tier policing. That's what's angered people and triggered the avoidable racial tension. But I also think that's what the establishment wants. If we're all fighting each other, we're not looking up to see the globalists from every country who are screwing everyone over.
I don't agree with any type of racism (towards white people, blacks or anyone else). Instead of addressing the root cause (systemic anti-white bias) the system itself has cultivated a hostile environment that encourages the worst traits of human behaviour.
The answer is non-violent action, open debate, and calling out the psyops that are being deployed against us, not only in the UK but across the western world.
