My parents will not accept me for who I am. Please read!?

My parents do not accept me for who I am. Period. I want to become a fashion designer, fashion is my true love. I also plan to begin a fashion blog, as I also have a talent for writing. My mother says fashion designers "end up working in sweatshops," however my Dad likes my designs, and supports me. Also, I am pretty much stuck at home since I am 14, so I don't have a car or anything, and my parents don't go out much, since my Mom is a stay-at-home-mom and my Dad works from his home office. So I never get to go shopping, and the few times I do, my Mom won't let me buy anything I want. I want to wear Forever 21 because I am bored silly of wearing Hollister all the time, but she thinks the clothes look like garbage. You and I know Forever 21 is a very popular brand! It is not garbage. She also won't let me wear glitter on my eyes. But what's worse, is that I tend to like gay guys. I like the androgynous look. My Dad is a total , and my Mom can be, too. They keep thinking I'm gay since I like gay guys so much. I am completely straight. They also don't support gay marriage. It saddens me that they can not be more open minded, and accept me for who I really am. What can I do?
