How to scare this 5th grader away?

From personal experience, i went up to the person who was making fun of me for my eyes and told him to stop. "Look, i dont even know you or talk to you, but i want you to stop making fun of me. I can report you to anyone at anytime to teachers, the principle, even your parents. This is your last warning or I WILL tell someone!" I was all serious and worked up, pretty angry when i told him this since ive basically had it with this kid. But if that doesnt work scare him or doesnt take you seriously add "Look kid, i know that you know i can kick your *** anytime, and if you wont stop i seriously will if i have too" dont do anything though just use words to scare him off, but definately, you MUST tell someone no matter what if it continues. Kids can get in deep trouble for bullying of any kind and warning from adults will stop them, and adults will take action. Especially since this twerp is younger than you, it shouldnt be that hard to scare him off. I know others say you might be stooping down to the persons level by doing so or by using force but seriously, my parents taught me if you need to defend yourself, do it. If someone beats you up, fight back and dont just stay still and not do anything. Do whats right. In karate, its a principle for using it as self defense that the enemy/person/attacker makes the first move physically, thats when your allowed to protect yourself. Im not saying you should use force at all, but just stand up for yourself, think before you act, but if you need to do what needs to be done, do it. Ive had enough with racist remarks in my life and dealt with a handful of situations to know whats up. p.s sorry for becoming a little too passioned, it just gets me worked up remembering my experiences and hearing about others who are being hurt for something they cant control such as appearance. Best of Luck!

There's no need to get aggressive with this kid, if you go to far and hit him, you're going to look like the bad guy. Instead you need to be assertive, explain to him firmly that you don't appreciate him annoying you like that and request politely that he stops. Again remember not to get aggressive. If this doesn't work, go talk to his parents or some teachers or someone of some authority that may be able to help.
