Why are kids so racist?

I can’t even go one day without some white kid who feels the need to call me the n word (hard r not to mention and have the audacity to dab me up) and/or when the class is watching a movie whenever they see a black guy they’d either say I look like him or he looks like a monkey, why are people so racist these days?

There was another time when the class was watching a video a monkey appeared on the screen and people started clowning me saying I look like the monkey
