Why are racial slurs and rude behavior so common with teens now?

My 7th grade niece has been telling me about how rude everyone is right now, An 8th grader shoved her in the hallway and just said "move *racial slur*" and I guess racial slurs are super popular right now. I've heard so many latinos and latinas saying it too, it's an african-american term only for african-american people, but nobody is gonna stop them either.

Also White people say it too, I am not saying it's one race who says it the most but from experience hispanics and latinos have been saying it.
