Is there anything I can do to stay with my girlfriend and not feel the pain that I do?

I have been going out with my girlfriend since May 20, 2009. We're in love, we've been through everything. I know that it is real and not just some kiddie relationship. However, her parents do not accept the idea of "us". This never mattered to both of us, until I realized WHY they do not accept us. She is white, and i am black, and her dad is a racist. He does not want his daughter to date a "black" guy. He feels it is bad for her rep. I have to deal with this every single day and it hurts, but its not HER fault. She understands, and she does not follow this racist thought process, however, we are both 17, therefore there is nothing she can DO about it at this point. Regardless though, I still hurt everyday. We have to sneak around all of the time, and when i'm with her, im happy as can be, but when im not, and RESTRICTED from talking to her (which is often), it hurts. She tries her best to make me feel better, but at the end of the day, theres not much she can do to stop me from being a victim of racism. What should/can i do? If i stay, then I will be happy with her, but I will have to deal with the racism factor everyday. If i leave, the racism wont die out, but it wont restrict me from anything at that point, but I will have to lose my girlfriend who is perfect for me.
