It’s more to highlight that not having a home is not a defining characteristic of who someone is, it’s a situation that anyone could find themselves in. It’s actually trying to dismantle stereotypes by showing that it isn’t some specific group of people. It’s not just changing terminology bc homeless is an insult, it’s changing it because the way that we speak about people can have a huge impact on how those same people are viewed. Homeless drug addict has a different connotation that unhoused person struggling with addiction, yknow? No one is pretending that it has a different meaning, it’s just about being respectful towards others. We can’t dismantle stereotyping without first recognizing the terminology associated with it. Just like “Jap” and “Japanese” have much different associations with them, despite “technically” meaning the same thing (i’m asian btw, that’s why i’m using it as an example, i’m not trying to say that homeless is a slur.) Hope this helps.
