Should i fight this racist guy?

There is this guy in High school i know who needs an *** whoopin'. I think i can beat him thats for sure!! He keeps calling me racist stuff like the N-word. He only acts thoug when he is with he's friends or girls or far away from me, then he just yell some racist sh** (he is white. Im black) when iam at a party and meets him he is like "Dude the party dies out soon, my dad drives me home wanna join?" and he dosen't drink so its not bcuz of the alcohol. And he always smile and give me a handshake when i see him in the mall. But anyways i have been working out lately and im planning to work out the whole summer, so i can beat him up the next 2 years and kill his rep >:) and become the bully he will never forget!!! I think he is scared of me bcuz he dissed this Asian girl and I threw a yo mamma joke at him and pushed him away and he was surprised and walked away without saying anything. So should i fight this racist guy? Im not gonna tell what he says to any adults and im not scared of his skinny jersey shore wannabe friends, i think i can beat up 3 of them with 1 hand. Im 100 % sure i win the fight. PS: im a black kid who lives in Italy so my english is very bad...
