What can I do and who can I go to get anyone to let me be myself?

An interviewer once asked John Wayne something like that. His answer was "Don't offend people accidentally." Then he went on to explain: "I think I have good enough taste that I can avoid offending people when I don't intend to."

My own take on that subject is that you can not offend someone, they have to *take* offense. All you can do is to avoid speaking one of their code words. But it still boils down to learning good taste. You do that by taking acting classes. A bonus is that vocal skill, such as drama or story telling, will improve your earning power more than any other detail. While you are at the local college, also take classes in civics and personal finance, since you need those and public schools don't teach any such thing.
