Ask google "is the ethos of libraries to help the homeless"
Here's what it says: The core ethos of libraries is to provide universal, equitable access to information, resources, and safe spaces for all members of a community, including people experiencing homelessness. While public libraries are not specifically designed to be homeless shelters or social service agencies, their foundational commitment to inclusivity means they naturally serve as a vital lifeline for marginalized populations.
This has always been the case.
The problem with reimagining the role of publicly funded institutions and ascribing a new "ethos" to them that is not supported by the public is that funding gets cut and libraries get shut down.
If you want to know the original ethos of libraries, it was to disseminate knowledge at low cost to members of the community. Not to be socially inclusive. Not to make people feel welcome. Not to provide "safe spaces". But to provide access to knowledge. By subverting this ethos, we have also subverted a lot of the funding model and political support, which is why libraries are having a difficult time right now.
it was formalized in the 60's but there was a precedent going back AT LEAST to the wild west.
You're clearly a right wing nut (since "libraries are more than buildings with books" is something you find "poltiical" and facts are something to be rejected), just come out and say it.
