No, we are quite literally related to those very people who looted and pillaged you. The early Vedic people who spread Hinduism via warfare/migration started in the Indus, the Scythians, Kushans, and Huns were all Eastern Iranics (just like the Pashtuns), Menander was from Sialkot, Timur, Babur and Humayun were Persianised Turco-Mongols (just like the Hazaras), Akbar was from Umerkot, the Ghurids, Suris, Lodis and Durranis were all Pashtuns, Mir Chakar Rind was Balochi, Jasrath Khokhar and Shahbaz Kamboh were Punjabi, Tipu Sultan's family was originally from the Punjab, Ali Sher Rai Anchan was from Gilgit Baltistan, we have a large population of Ashrafs descended from the Islamic invaders and many people from what is now Pakistan also fought in their armies as ghazis.
All of these groups/peoples went to what is now the Republic of India, burnt its cities and washed its streets in blood. Learn to live with it.
