I mean with things like sex trafficking, labor trafficking, etc. IMO it should be called slavery, and those affected need to be rescued from slavery.
A pimp enslaves people
The Tate Brothers (allegedly) enslaved people.
IMO, referring to sex/labor trafficking to slavery will show it just how evil it actually is.
I say they all have equally horrific connotation. But “forced labor” sounds like “slavery lite edition” when I read it.
