You did not tell me the reasons for not allowing Pakistani patients ?
As far as your question why they should be allowed? my answer is
Because when your government can sell your blood for trade with Pakistan and you Indians members can compromise on your emotional stance viz a viz contacts with Pakistan and come to a Pakistani forum then why subject patients to your hate ?
When you can be ok with Pakistani cement and ofcourse with Pakistani ONIONS
then why sudden rush of ghairat over when it comes to Pakistani patients.
