No doubt there are minority groups in Iran, but close analysis of mtDNA reveals there are no differences between Iranians and Iraquis (for one thing), and little differences between that cluster and other Semites in the Middle East.
You must be referring to LATER developments such as the new ethnic group called Palestinian ~ with the Ayatollahs simply importing them to do all the wet work.
Look, you've got several thousand years of history there and the glyphs don't lie. Persians do that stuff and always have.
Did you ever live there? It is vey well documented that the current regime has hired these mercs to keep control in the country. Now if we want to talk about all the nasty stuff that every society has bestowed upon its people in the past, then no arguement, but, to equate the actions of past societies on todays thinking is fruitless.
Persians are NOT a semite people! They are the source of the Caucasian races as the Indo-European races come from the Caucuses region north of Iran. Iran means Aryan.
If Persian people 5,000 years ago behaved in a cruder fashion than we do today that is a matter of evolution. In those days the average height of a man was about FOUR feet tall and they were hairy,nasty little creatures.
What twisted logic and again lack of decent information on the subject.
Sheesh!
