Ignorance breeds fear and fear breeds bullies. Bullies are really just people who are afraid of people like you, or anyone who is different from them. It starts on the playground with hair length and clothing choice and continues into high school and adulthood with racism, misogony and bigotry. Learning to stand up to people who are bullies is a lifelong battle I'm afraid, but one that is important to learn early. Don't let anyone define what clothes you should wear, how long your hair should be or who you should choose for friends. Keep standing up for yourself and know the words of Eleanor Roosevelt: "Remember always that you not only have the right to be an individual, you have an obligation to be one" and "No one can make you feel inferior without your consent."
Because here's the thing about bullies: they only pick on those who they feel are weaker than they are. Most bullies want an audience, to feel better than everyone else by making others feel small. My best advice to you for this age is to not provide that audience. Walk away and live your best life on that playground. Go swing on those monkey bars, sled down that hill and play with the people who have your back. Show them that you will not allow yourself to be bullied. As Michelle Obama recently said, "When they go low, you go high."
