Crap! My girlfriend's mom is racist. What do I do?

Hello everyone, i'm a new user. So this is my first question with a problem that will follow me through out the rest of my relationship. Recently I've found out, that my girlfriends mom is racist. Me being (black) My girlfriend (white), she explained to me that it doesn't effect her opinion on me at all. Which is awesome, the problem is I will not be able to take her out on dates or be able to hangout with friends. We are 16 years old and it's effecting are relationship a lot, I just need advice on how to handle the situation as far as what to do. So should leave her? Try and communicate with her mom, because her mom hasn't met me, nor will she even try and meet me. Or should I just wait until something happens, I'm really confused and desperate for advice. Please help, my greatest appreciation and deepest thanks

So here's an update. She calls me asking if I wanna take pictures with her, which caught me off guard. This has brought up a lot of questions in my head, but the main one is whether I should go or not. Like what if her mom finds out? She told me her sister in-law was going to take them for us, I don't want to cause more family drama between her and her mom. Also I don't want to disrespect her mom, by going behind her back. Should I go and take the pictures, or just call it off?
