Is this cled as racist?

I am a bengali, muslim. I go to a school, I have white people going to my school. They say I am afghan, they say I am a taliban, They say I am a terrorist, stop bombing houses, stop using grenades and they say stop throwing grenades. This boy had a mive cut in his hand and he says that I shot him with a ak47. They say I wear turbans and everything. Is this racist?
