Pride and Prejudice

I watched the movie "Crash" with my husband yesterday morning. It is interesting to me how prejudices reach across every line and how everybody has them. This movie showed in an unflinchingly profound way how deep they run. Every country, culture, and creed is touched by prejudices, wars are started because of them, and whole races of people are becoming endangered because prejudices dictates so much of how we interact with one another. It made me think a lot about my own heart. What could I change? What prejudices have I developed under the guise of self-preservation? I will tell you if you are easily offended by language, and you do not have a DVD player with a language filter, you may want to refrain from watching this movie. I personally want my teenage daughters to watch it with me (editing out a couple brief scenes) because the way the topic is presented, poignantly and without a cheesy resolution. The movie touches on some nerves I think we need reminded are still there.
On another note about prejudices, we have a new Valero store that has opened in our town by people of Middle Eastern descent. Yesterday, I went inside while my husband and kids waited outside because the machine was not taking my debit card. When I went in there was some cultural music emanating loudly from the computer on the counter, and an older man shouted in a foreign language at the teenage boy who promptly cut it off. The man behind the counter told me to come back in and pay after I had pumped my gas. When I went back in my husband went with me to get a cup of coffee. The men did not even know I was there. I was the one making the transaction, and the clerk would only speak to my husband, "How are you today SIR?" (his emphasis not mine!) I was slightly offended. I understand it is a cultural thing, however, there is a part of me that realizes as a woman I would be expected to blend into the standards of their culture if I lived there, and I feel like they should do the same in this culture. Is that a prejudice? I've got a long way to go!
