>The Baloch definitely should be allowed to vote.

When Pakistan does, message me again. I'll personally support a referendum vote in J&K. 

>I doubt Sindhis will ever vote to secede from Pakistan

Read about GM Syed, Jyeah Sindh movement and Sindhudesh.

>I also doubt Balochistan would actually vote to secede

And I doubt the majority in Indian J&K would vote for secession either. Kashmiri Muslims are only 40% of Indian J&K and even among them 5-10% are pro-Indian. So, let's do neither.

>Typically people don't leave a country that is working for them.

Its a hypothetical, so it doesn't matter. Plenty of rich provinces want to secede, only for their sister provinces to be pissed off because they believed that they only get wealthy because of federal or their help. Kashmir did too. India financed and still finances Kashmir on a debt. Pre-2019, they received electricity subsidies because of federal grants. When it was cut off and made equal, they protested and cried the same way again. Its an itch against equality here. 

> now the Indian people want to remove that culture

Because its not our culture. Are Persians not for their own culture? They are too and so are the Arabs. Why should ANY foreign culture trump our own and those of our ancestors before the foreign tyrants came in? Same applies for Pakistan. Why copy and larp the Persians or Arabs or Turks when you're your own? Why think Bin Qasim was the first Pakistani?

>But more importantly, Punjab doesn't try to distance itself from it's Persianized history; India does.

First, Punjab is IN India and Indian. Second, its not a problem as you say. Biryani is foreign but we fully accept it. Idk about others but the average Indian is not throwing away foreign culture, that is natural and even beautiful. My culture has more Portuguese influence and even foods. We don't reject it, regardless of the rather bloody history. However, is it wrong to say our OWN culture should be our priority? When our native culture is superseded, that becomes a problem.

>Talk to Syrians, Palestinians, Egyptians, Somalis, etc.

First, not real Arabs. Second, seriously? Only reason they don't do it as much is because they're poor as well and have no reason to boast themselves. But even then, they're pretty racist especially the fairest among them. However, that's not even the most important here. An Arab will still choose another over a Pakistani, regardless of faith. If you know them, you'd know this very clearly. Has nothing to do with race or skin colour even. They even accept Sudanese before they accept a Punjabi. The cultural difference is huge but then the Lahori will enjoy a Chicken 65 from a pakka Tamizhan from Madurai.
