Well, there are stereotypes about all people from every walk of life. People with glasses, office workers, musicians, redheads, politicians, homemakers, librarians, bankers, actors, people with tattoos, women who wear skirts, women who wear pants, men with long hair, whatever. If you have any identifying details about you at all, some one will probably use it to jump to conclusions about you. Probably without even realizing it. And there's nothing you can do about that. As people get to know you, they will realize that their preconceived notions are false. If they hang onto them, despite knowing you well enough to realize they're wrong, that's when you know that the person may not be worth knowing.
