Its not the 75 million Persians you need to worry about, its the handful of Shiia Twelvers who rule the country that are the bad actors. Regular Persians have said that they would gladly die to free their country from the 12ers.
Those "Twelvers" are a product of their up-bring. They learned their "bad acting" at the knees of their mothers.
I learned to dislike the Persian/Iranian attitude a long time ago. The word "aryan" (forming the country IRAN) means PURE, by the way, and they do consider themselves the PURE race.
That is where Hitler got his "pure race" crap.
