I am not talking about muslims harming Christians. I am talking about Valmikis following muslims from east punjab into west Punjab. Why would they do so? Dalits did follow Jogendra nath mandal into Bangladesh but haven't heard of them moving to west Punjab.
You are judging them by caste. I was guessing they are Dalits, but I don't know because Christians are a bit different looking than Muslims in Punjab. They tend to be darker and have smaller noses.
I think the difficulty you are having is accepting that when they become Christians, they become a community separate from any caste as you may know it. Same for Muslims in Punjab, our family names become tribal identities like Pukhtoons and Baloch, instead of social class.
We freely intermarry with each other in Pakistan, regardless.
I've noticed the same thing about your Parsis.
The way they dress and speak and wear their hair.
Even how they trim their beards.
Honestly, you cannot tell Parsis apart from Muslims, even by name as many Pakistani Muslims have Persian origin names and blood too.
I don't know details about Parsis as I am from Punjab, which has mostly Christian minorities and Sikhs.
You will have to ask people from Karachi.
Also the Grand Mufti of Palestine was aligned with the Axis powers and the Zionist movement was already established even before the 2nd world war. Jews escaping holocaust weren't allowed to land in Haiffa and the Zionists had to go the extra mile to make them land.
Patel was willing to sacrifice kashmir for Hyderabad and that would have saved many lives of muslims also. But Liqauat Ali Khan said no.
Your information about Palestine is eschewed toward Israeli propaganda. The Grand Mufti was a single actor, who approached all European leaders, not just Hitler. He did not have much power himself, but he was trying to stop unbridled Jewish settlement in the Holy Land. He saw the disaster that was happening to his people. His prediction came true.
British and Nehru/Gandhi really blotched the partition for Pakistan. We got the raw end of the deal. We lost 1/2 Kashmir and Jammu demography was altered forever. We lost 1 million people in Punjab and 14 million we had to absorb as refugees. East Pakistan was ripe for separation.
This was not what Quaid wanted, and still the partition is unfinished as Delhi riots and Kashmir lockdown show.
