In the case of these two countries many people had the chance and they did migrate the largest migration probably in recent history if i am not wrong, those who stayed here wanted to be a part of this country those who left opted for India this country was created to safeguard Muslims and to establish an Islamic state if the minorities chose to stay here and if they aren't protesting everyday or every week on the streets like Kashmiris are then it means they know they aren't being targetted because of their religion. The majority overhere is being targetted its not the other way round.
