The guy starts this documentary with "first thing you need to know, iranians are not Arabs, they're persians",
there is much more propaganda and false lines in it, but this is the very first one the documentary starts (after the opening scene). Its completely false and lacks facts;
Iranians are heterogeneous ethnic groups of people making up Iran, consisting of Arabs, Turks(Azeri), Turkimens, Kurds, Baluchs, Lurs etc and Persians..
When someone starts a documentary with such blatant ignorance, it turns me off from watching it and it pushes me to label it another subtle anti-islamic republic documentary.
I'm still going to watch it to see it's direction. But from the beginning it's clear.
Sometimes the translation is also off, changing the meaning of what is being said.
Yeki be nal, yeki be mikh.
