What to do about racist kids?

I’m a junior and I go to my favorite teacher’s class during the day and there’s always these racist ass freshmen and sophomores at are always saying racist shit. They’re making jokes about Africans and Mexicans. They always have segregation jokes. This one kid made a joke about George Floyd. I’m about sick and tired of it at this point. I’m 2 seconds always from snapping at them. But I don’t wanna look like an angry black woman. Should I speak up?
