And being Iranian, as I assume you are since you claim the 2500 year old persian empire as your "heritage", you would do well to note that the empire started by cyrus bears no resemblance to modern iran. Cyrus was an advocate for human rights and freedom of religion for everyone. He was also a great friend to the jews. That kingdom was later conquered by the macedonians, the byzantines, the mongols, the turks and many more, but most importantly, by the arab empire which effectively setup the "heritage" you claim. You share nothing in common with the persians of 2500 years ago, so get over it.
My point is the early culture of the first persian empire is not your heritage and has no bearing on iran today. That was 2500 years ago. Your heritage is arab because that was the last culture to conquer persia and it still holds sway today.
I asked two questions in the last post. You ignored both so I'll ask again. What social or philosophical "heritage" from the early persian empire is espoused in modern iranian culture? It's certainly not cyrus' bill of human rights. And also, what makes persia's being conquered by arab invaders any different than egypt's being conquered by arab invaders?
