your statement rests on the assumption that india/pak as they're now would be existing if and when a sikh state comes into existence on the face of subcontinent.
the last time the sikh empire emerged was when two superpowers of marathas and abdalis annihilated each other in the battle of panipat and the power vacuum thus left was soon filled by the rising sikh misls.
I can imagine the controversy between Sikhs themselves regarding what type of nation a hypothetical Sikh country should be. Ethno-state or secular? The hardcore will predictably want something akin to a Sikh North Korea, while the far-left Twitter poseurs will be angling for gay-pride parades and trans-Anand Karajs.
Let's not be under misapprehensions: from day one India and Pakistan will dedicate a significant portion of their defence budgets to destabilise a Sikh state. They will throw everything they have at it. We'll need our brightest and our best to counteract it all. 😀
You make a valid point. If the ancient Afghan Buddhists had been like this there is no way Islam would have taken root in there land. The problem with these Abrahamic religions is that they hate Dharmic religions to the core. That is why you see some modern missionary influenced Khalistanis like Udoke and Makhu who try to Abrahamize Sikhism in order to make it more palatable for there Muslim friends.
Currently Sikhs in India are opening up their doors to the Abrahamics and you can see how Christianity has spread all over Punjab. Even Islam is once again taking root in Punjab thanks to Sikhs building mosques for them and giving our Gurdwaras to be used as semi Mosques where they can come and do there Namaz and celebrate Eid which as we all know is against Gur Maryadha.
Of course some Sikhs partly do this moorkhta to annoy Hindus by showing closeness to Muslims and Christians. But you don't have you shoot yourself in the foot to annoy Hindus as we are doing now.
