Whether you want to accept it or not, it is your insecurities. You did not answer my above question. Even if you think it was a stereotyping, then do you think your race or culture is free of stereotyping? It is a human nature. Fact-everybody on this planet does that.
I  agree it is a nation of immigrants. Her great-great Irish grandfather probably faced the same problem like you. It's nothing personal. Assuming things are human nature related, not attached to countries and origin.
If you feel yourself so smart to call me a "moron", why not we hear you spoken English? That will clear out some misunderstanding.
No offense.
