Hi. Although my country (Iran) has a rich culture and history, but we don't have many tourists from all over the world (you know, because of policy). Most of them are Arabs and as you said the altitude of my people about them is very negative. I don't want to talk about it because it's very racist. But I think this kind of altitude about foreigners is common among all the people living on earth (even among aliens)!
I think people should change the way of their thinking and make the world a better place like the one that John Lennon (R.I.P.) showed us in the song Imagine.
I hope someday you visit Iran and I guarantee you're gonna enjoy it :-)
