Replying to Help Please. i could get expelled

ok so i was at school and i found a motivation poster in my schools my documents folder. it was a picture of a pair of lips surrounded by 4 white triangles(aka a black person surrounded by the kkk). it said ABSTRACT ART  "its all about how you interpret it". so the my teacher saw it and took it. now my school suspended me for a week and is trying to expel me or get me sent to another school.
