Yoko,
That is exactly how I feel. It is difficult to keep the stereotypes we hear every day from influencing us. I hate it when I react (even just inside where nobody sees) in a prejudiced manner. I know better. And yet, when I least expect it, it sneaks back in. Usually, because I have allowed myself to get so caught up in my day-to-day physical reality, that I lose sight of my spiritual self. So, I just keep trying. Slowly but surely, perfecting my world view.
