I'm really not seeing what you're complaining about unless you have some "all lives matter"-esque point that you're trying to make. Nobody's communication is being impeded by saying "let's stop sex trafficking" instead of "let's stop sexual slavery" and nobody's behaviour is going to be different on hearing those two sentences and nobody is going to pass different laws or behave differently in any way. I hadn't even thought of those two as separate previously but even taking the effort to mentally separate them to argue with you, I don't feel enlightened or challenged to act differently. There's nobody out there saying "Trafficking is bad but slavery is a-OK!". I really don't know where you're going with this.
Why did we feel the need to isolate a minor aspect of slavery, teach everyone the new term, and then arouse outrage against it, instead of simply organizing against "slavery", which had already been considered wrong for generations?
