Genetics may not be a subject in madrassas, but believe me human race evolution has to do a lot with genetics. Brazilians and Argentinians resemble southern Europeans because South America was under colonial rule of Portugal and Spain. And lot of people from Portugal and Spain have settled there since then.
Indians don't have any problem whether Pakistanis being Arabs, Turks or Persians. It is Arabs, Turks and Iranians that have problem with Pakistanis calling themselves Arabs and Turks
My advice: Educate Arabs, Turks and Iranians of you being Arabs, Turks or Persian and not us Indians. You can start with educating
