Actually we have more than one Shahbazi in this field, and people sometimes gets confused about them. I will send you their interview in youtube if I find them. You may also know Ghias aabaadi as well. he is an ultra pan persian, but he still has respect for Pourpirar. They are many like these guys.Anyway, about being a persian, at least it voids the argument that he is an ethnic arab who is a hardcore Pan-Arab, which it claimed by some users here. Anyway, I have worked on Cuneiform some years ago, when I was in high school, and middle school, and then this experience helped me a lot to understand that most of the quotes about those era are simply BS. since it is literally impossible to understand those languages, and they use very stupid and inaccurate ways to just guess what is written. So, I just laugh very hard when people tell me that Cyrus has said this or that. Some languages are readable, though, like ancient greek, but many of the remaining greek writings that are found in Iran, contradict what Iranologists have told us. There are tons of examples for it. I can mention you many examples of them.
