You are not a racist madam, you are a xenophobe. Do you know the difference professor? Plus these are not nationalities, there is only one nationality, Pakistani, these are ethnicities. Get a book professor, have a read of something worthwhile and stop talking like a sore loser. Sindiyon ka naam kharab mat karo. Be less jahil, live longer - public service message for all ignorants like Prof. Falani.
