Why do so many people hate Iranians and where does this hostility come from?

What have they done to you personally? Is it because you hate their religion for some reason? Or because you resent the price of gas and blame it on them or because of their religious beliefs that conflict with yours? What's the deal with us? Do you even know any of these people? I've worked with a lot of Iranians and they in person are a pleasure to work with and make good friends. I don't understand all the hostility.
