Pakistan ka matlab kya "La Ilaha Ilal la" which means Pakistan is a Islamic state.
Moreover Pakistan was created because Muslims were persecuted and so it has been created as a safe haven for muslims of subcontinent and neighbouring areas. So why don't you provide safety to Rohingya or Afghans?
I've already explained to you it was only ever intended for the muslims of north west Indian sub continent I.e pakistan. When later the bengalis wanted to join the movement initially baba jinnah was reluctant . There are over 1 billion muslims practically speaking the all can't live in pakistan and it was never intended to be a homeland for all muslims to start with.
