Damn guys....try not to be as nationalistic as Abu Jahal or like Trump supporters.
We Muslims are One Ummah....anyone saying otherwise is going back on the words spoken by the Prophet SAW....so your issue is with his SAW word and what Allah SWT decreed.
There is no nationalism within Islam.....if you repeat bs like "ummah chummah" then you better pack your bags and get a flight to Texas since I'm sure these guys will like you here. You know...they hate Mexicans as much you hate Indian Muslims.
Going onto serious stuff.....current generation of Indian Muslims has done no wrong!
Don't put burden on them for what their forefathers did...that is, not go and immigrate to Pakistan.
Again, not everybody had the courage to immigrate or the resources or the hope....we're not robots, we're humans, each human being has a different set of life choices. Just because your forefathers choose to move doesn't make others life decision bad (even if they are lol).
Now that the Indian Muslims have realised their mistakes, we should be helping them...not creating uber nationalistic fervours among us like Nazis or Trumptards (Trump supporters here in the US).
Fight, verbally, for the rights of Indian Muslims and later on, beseech the Pakistani govt. to let them into Pakistan, if needed, or/& provide them with the right equipment to start independence movements within India and help them carve a place within India.
Allah SWT is the giver, provider & sustainer. Don't worry that your country will be over flooded with refugees. That is such a despicable line of thought. Try not to go there...I know the Prophet SAW & the Shahabah wouldn't have thought like that!
Mic drop!
