Is it possible to legally disown my Mom? Pleze read and respond, and I will be very grateful to you?

I hate my Mom very much, and my reasons aren't just the usual shallow, self-centered reasons of a teen. I actually have real problems with this woman. She has hurt me, frustated me, and made me cry so much, that it wouldn't be possible to ever rekindle a relationship with her. First of all, my Mom is anti American. She is an Islamic woman who immigrated here from Iraq and then raised me and my 2 sisters. She raised my sisters and I just like any other American has ever been raised. English is my first language, I don't know anything about Iraq, I only know about my own American culture. So, to clear that up, I am American, but my Mom is not. Today, she said something that had me agape at her sheer ignorance. I was rejoicing at the news of Osama bin laden's demise, and she had the utter audacity to claim that Americans were the real terrorists, and they were just attacking Islamic culture. At first, I couldn't believe my ears, and thought that I must have heard wrong. Did she not know what happened on September 1, 2001? Did she hate Western culture that much? Being American, I was so infuriated that I had to run out of there before I said something that I would probably regret in some way or another. My Mom and I have nothing in common. I grew up living the American way of life, but she was an Arab. I am absolutely disgusted by my Arab heritage, and I think Islam is a very primitive and barbaric religion, and I refuse to believe in it. I am actually an atheist who believes that science and religion contradict each other, but I cannot share my beliefs with my Mom. Also, I am a liberal, and yet she is a conservative. Moreover, I am a , and when I told my Mother one time that I supported same- marriage( because I am a myself) she told me that I was brainwashed and yelled at me about "supporting disgusting *******". She fails to realize that being gay is just like having a certain personality, we are just wired that way. These are not the only issues I have with my Mom, by any means, and if I ever had any respect for her, I lost it a long time ago. She is not a Mother to me, and I absolutely hate her, and my idiot sisters who can't think for themselves, but just accept whatever the hell that ignorant excuse for a parent tells them! I hate all of them, can I legally disown them and, perhaps, live with a friend. I am 14 years old, btw. I promise this is a serious question, and everything I said about my own Mother's ideals is true, so please make your answer serious!
