All ive seen on why I should use unhoused is because conservatives have tried to weaponize the word homeless into a pejorative term to blame the victim. Which means we are picking a new term to make people feel better about the issue and the consensus still seems to be homeless people say homeless.
I would argue people would think being in a shelter makes you stop being unhoused while you are still very much homeless. Homeless reminds you the issue is that we can not get homes, just shelter. But maybe it makes people who feel the same while being better off feel bad idk.
It’s like a return to hoovervilles. Sure there is shelter and it’s quasi housing but I doubt anyone in them at the time would call it a home. It’s not the word that is the problem but how people feel about the issue. A word change won’t change that entirely just confuse the dumber people for a minute while they catch up.
