Why are British people, who are usually against racial slurs, okay with slurs that are class-based, such as "chav"? - Lemmy.World

I learned a new word, and it turns out the word is a slur for a person who is working class. That seems very nasty, considering that statistically speaking, working class people are the majority of Britain. Most British people I know online are against racial slurs yet throw around the slur “chav” like it’s nothing. Why?
