No they are not. 'Death to America' is not the same as 'Death to individual Americans'. Perhaps you should consider that your reaction of believing that it is a personal attack on you and your loved ones is the result of anti-Iranian propaganda as much as Iranian animus (and propagandization of Iranians).
I don't think you really believe that Iranians are lying awake at night trying to figure out how to destroy you, plandis. They're not even reading Hacker News and thinking 'Death to America and plandis in particular'. If you think about it, you probably recognize that their gripe is with the American presence that surrounds their country - look at the huge number of US bases in the region, in addition to the history we're discussing here. It's not like the Iranians have a ring of bases in Canada and the US, is it now?
My study of American history has led me to support the idea of ending the government of the United States as it currently exists. We'd menace a lot fewer innocent people if the union were chopped up into about twenty pieces.
Here is one such instance from the recent past: https://www.reuters.com/article/us-iran-usa-embassy/iranians...
