With some emotional pitch I raised my voice:

“My Sisters and Brothers: Tell me: who killed the first Prime Minister of Pakistan- Liyakat Ali Khan? Who killed the elected President of Bangladesh- Mujibur Rehman and his family- men, women, children and grandchildren? Who hanged your elected Prime Minister Zulfikar Ali Bhutto? And who removed the elected PM Shrief at the gun point and declared himself President of Pakistan? Is he your brother ? And the Babar was your brother ? But Buddha, Gandhi and we Indians, Hindus are not your brothers?”
And finally I asked :

“Had Holy Koran defined the Blood-group of the Muslims? What is the Blood Group of Pakistanis that separates you from us Indians? And how do you separate Shias and Sunnys blood-groups?

When Pakistanis come to India for medical treatment , the blood given to them is donated by the Hindus. Our doctors match the blood group of the patients, not by Islamic shariat. There is no exclusive blood group of Muslims.”

As I ended my lecture, clapping was subdued but I received many shake-hands and words of the scientific recognition.
