The supreme irony here is that Ms. Khan's ancestors were one the most enslaving people in history. There are 57 Muslim dominant countries in the world today . Did Ms. Khan ancestors ask politely to enter those countries and spread their religion ? We know differently.  For example , Afghanistan was once a Buddhist country . The Muslims invaded and slowly destroyed all signs of Buddhist history. When the Taliban took over they destroyed 2000 year old statues and artifacts. ISIS did the same in Iraq , destroying ancient Assyrian and Babylonian artifacts because they interfered with the Islamic idea of history.   In Jerusalem the Muslims built the Al-Asqa Mosque in the 8th century on the site of the Jewish temple built by King Solomon in 957 BC to house the Ark of the Covenant. Muslims claim Jerusalem as theirs even though it was a Jewish city for almost 2000 years before Mohamed was born.
The British could have taken lessons on colonization from the Muslims of yore.
