Are caucasian high schoolers racist or is it just my school?

every high schooler I know that's white always says some stupid remark to latinos like me such as get the hell out of here you stupid mexican and laugh. The girls really don' say anything, but they don't date them because they aren't their type, but that feel like they're stereotyping is. Some girls who we sit beside in lunch because of lack of space always stare at us like "wtf weirdos sitting beside us" when we don't even say or so anything perverted. I'm not going to report this as a problem because prejudice is never stopped pf course. It just seems like we can't be a part of the same society it's ridiculous. Just a couple of months ago some teens at a Walmart yelled out at me and my sisters and her caucasian husband "s suck". It's just stupid and it feels to me like this won't ever stop. Is it like this at all the schools.
