> The words "house" and "home" mean different things.
A house is a physical dwelling unit for humans to occupy. It's a building. A home often implies a place you reside, where you find safety and joy. The difference between these concepts gives rise to the common expression "make this house a home".
People can have homes, even without a house. For instance, a digital nomad might live in an RV or van. They would call it home, but not a house.
> "Houseless" is more correct than "homeless"
If we decouple the idea of a physical house from the idea of a home, then "homeless" people might actually have homes -- a spot they feel secure in, a place they return to.
So calling them homeless is incorrect. One can have a home but not have a house.
> except that not all housing is houses, so you'd have to make it "housingless",
Many things aren't "houses" per se, though they are housing. Apartments aren't houses, condos aren't houses, RVs aren't houses, etc. The umbrella term for house structures is "housing". These people lack housing of any type, not homes, so they could be called "housingless".
> and "unhoused" is far less clumsy.
This person would rather say "unhoused" vs "housingless", because they find it easier to say.
Hope that's clarifying. I'm not interested in discussing whether the terms are good or bad. You can disagree with their use and keep using "homeless" for all I care.
I just want you to understand the post being presented. Again, feel free to disagree, I just don't want you to feel like "I don't understand the reasoning".
